The two cards he has already read forty times

Most son-in-law cards in the shop reach for one of two scripts and both of them lie. The first is the welcome-to-the-family one. Welcome to the family, son. I always wanted a son and now I have one. You are the son I never had. Skip every line in that family. It patronises the son-in-law by making him an honorary biological child, it patronises your daughter by suggesting her partner only became real once your seal of approval landed on his head, and it overclaims a closeness that may be eighteen months old or twenty-two years old, but in either case is not yours to inflate to order. The second is the joke-shop register, the in-law-jokes shelf at the back of WHSmith, the cartoon son-in-law with the football shirt and the empty beer can on the sofa, the punchline he has been the butt of for forty years on television. Skip it too. Almost no real living son-in-law wants to read a card that opens with either of those.

The honest card sits somewhere quieter than either. Name the one thing he actually does. The repair he keeps making in your house. The dish he learned from his own mother and has now cooked for your family more times than your own children have. The route he takes the long way out of town on the drive back to the flat because of one specific roundabout he has views about. The team he supports. The half-built project in his garage. The card lands when it names the man, not the role.

Here is the one thing nobody warns you about with this card. There is a third reader, and the third reader is not the person you might think. For the father-in-law card, the third reader is the spouse whose father he is. For the sister-in-law card, the third reader is the spouse whose sister she is. For the son-in-law card, the third reader is your own child. Your daughter, your son, the one who married this person. They will see what you wrote. They will read it before he does. Some of what you are doing on this card is a small love letter to your child about the partner they chose, and some of what you are doing is a card to him directly, and pretending only the second is true is what makes a lot of these cards ring slightly false. Write the card to him. Let your daughter or your son read it over your shoulder and feel what they feel. Do not write the card to your child with their husband's name on the envelope. And do not, on any account, write the card on the assumption that loving your daughter and loving the man she married are the same act. They are not. The first is the parent's deal. The second is something you earn into year by year, the same way he does.

And one note on what to call him. Some people use his first name. Some use a nickname the family started using on the second Christmas. Some use a relation word in a first language that the household uses for these things. Some use Son with a capital, and a few of those land and most do not. Sign it the way you address him in real life. If you have called him Tomasz for seven years and you suddenly write "Dear Son" because the card said so, he will hear the difference between the man you talk to and the man you wrote to, and it will not be the difference you wanted him to hear. For a biological son the wishes for son set fits the job; this one is for the man your child chose.

For the son-in-law you would choose again

This is the easy one, in the sense that your daughter or your son chose well and you have known for a while now that they did. You like him. You ring him about a thing he knows about that you do not, and he answers. You have started to count him in the household head count for Sunday lunch without thinking. The card needs to honour the weight of that without sliding into the welcome-to-the-family register. Name one concrete pattern. One sentence he said in October. One specific repair, one specific dish, one specific drive. The bigger lines do not work here; the daily evidence does.

  • Happy birthday to the son-in-law who, in seven years, has somehow become the man I ring first when something has gone wrong with the boiler.
  • You did not have to take on the wider family alongside Mhairi and you have done it anyway. Happy birthday, with everything I have.
  • You drove the stool back to me on the Sunday lunch the weekend after you fixed it for the third time, and you did not once mention that I had had nine months to ring you about it. Happy birthday.
  • You earned the place at this kitchen table the slow way, one Sunday at a time, and I noticed every single one of them.
  • Happy birthday. The wood glue you keep in your shed has fixed more of my house than I have, and I am quietly grateful and quietly embarrassed about both halves of that.
  • You have loved my daughter without trying to remake her, which is the harder of the two jobs and the one I rate most.
  • You sat at the foot of the bed in Raigmore Hospital with us on the bad week last February and you said almost nothing for hours. That was the right amount.
  • Happy birthday. You have been a steady man in this household for seven years and that is a thing I do not take for granted in any year, including this one.
  • I have a child by birth and I have a son-in-law by her choosing, and the two of those are not the same thing, and I have got better at holding the difference. Happy birthday.
  • Happy birthday to the man my daughter chose, who I am, against all reasonable expectations, very glad she chose.

For the son-in-law you barely know yet

If the wedding was last August and this is the first or second birthday card you have ever signed for him, do not overreach. Newness is not a weakness. A card that admits, plainly, that the two of you are still working each other out lands better than a card that performs a decade of warmth in fifteen months. You may have spent forty hours total in his company, across two Christmases and a long-weekend trip to a cottage. Pick from those. The dinner where he asked you about your work in a way that suggested he had actually listened to the answer he had been given the time before. The morning he made the coffee before anyone else was up.

  • Happy birthday to the new son-in-law, fourteen months in, on the second birthday card I have ever signed for you.
  • You have made yourself welcome in our kitchen without making yourself the centre of it, which I appreciate more than you know. Happy birthday.
  • Happy birthday. We are still getting to know each other and I do not want to rush it.
  • You have been kind in the small ways from the start, which is the actual measure. Happy birthday from the new mother-in-law who is paying attention.
  • I do not yet know what I will call you in five years. The not knowing is comfortable, and I think that is a good sign. Happy birthday.
  • Happy birthday. You have known my daughter for less time than her old school friends have and you have given the family the same easy hospitality back as if you had been around since she was at primary. We have noticed.
  • I will not pretend I know you well yet. I am glad my daughter does, and I am taking the rest on her word for now. Happy birthday.
  • Happy birthday. Two Christmases in, and the second one was easier than the first one, which is exactly what it is meant to be.

For the long-married son-in-law who has basically been around forever

This is the son-in-law who has been around since the late nineties, since before two of your grandchildren were born, since before your spouse retired, since before your hair went the colour it is. He is basically a son in the family ledger. He is not, in the literal sense, your son, and the card has to keep that quiet line in view even after twenty-two years. Resist the welcome-to-the-family line. Name a specific stretch of years he carried, a specific big call he made, a specific quiet bit of his fathering or his husbanding that nobody else gave him credit for at the time.

  • Happy birthday to the son-in-law who has been at this kitchen table for twenty-two of these and counting.
  • You took the night shift the year Mhairi went back to work after the first baby, and you did it without ever once saying out loud that you were doing it. I noticed at the time.
  • You have been one of the quietest, steadiest men in this family for two decades, and I am unlikely to ever fully say that out loud over a Sunday lunch, which is what the birthday card is for.
  • Happy birthday. Twenty-two years in and you are still the one in this room who would notice first if I was off form.
  • You sold the bigger house and bought the smaller one when the youngest started university, and the way you held the family through that year is one of the things I have not forgotten. Happy birthday.
  • Happy birthday. We do not have one big speech for the long-married son-in-law. We have twenty-two regular Sundays a year, going back to 2003, and most of them have been good ones because you were in the room.
  • You have not tried to be my son and that is exactly why you have ended up something next to one. Happy birthday, Tomasz.
  • Happy birthday to the man who has done a quarter of a century of being good to my daughter without once asking to be thanked for it. The card is one of the thanks anyway.

For the son-in-law who lives far away

If he and your child live in another city, another country, another hemisphere, the relationship lives in airport pickups and group video calls and the WhatsApp thread you share with the two of them. The card has to live in that geography honestly. Skip the lines that pretend you see him weekly. Name the specific thing about the distance. The two weeks in summer when they come over and the kitchen runs on his coffee, the December video call where the time zones meant you waved at each other at 11pm his time, the run he and you did along the Ness on his last visit.

  • Happy birthday to the son-in-law I see for two weeks in July and a video call at New Year, and who is somehow still one of the family I count without checking.
  • You make the December video call land easier than it has any right to, given that it is your bedtime and our breakfast. Happy birthday from Inverness.
  • Happy birthday. The two weeks in summer when you and Mhairi come over are the weeks the kitchen runs on your coffee, and I have not had a decent flat white since you went back in August.
  • You have been good at the distance, in the small steady ways nobody writes a card about. Happy birthday from the mother-in-law on the other side of the time zones.
  • Happy birthday. The pickup from the airport in July is the thing I am secretly counting weeks to since about March, and I will pretend to be casual about it when you come through arrivals.
  • You moved my daughter to a country I had only ever flown over, and you have made it work, and you have made her happy in it, and that is the whole job. Happy birthday.
  • Happy birthday. The thing about loving someone who lives that far away is the long quiet stretches. We are doing alright at the quiet stretches. We have you to thank for some of that.

For the son-in-law whose first language is not yours

If he grew up speaking Polish, Punjabi, Gujarati, Cantonese, Tagalog, Portuguese, Italian, Hindi, Igbo, Tigrinya or any other first language, and yours is the one he lives in now, one line of the card in his language goes a long way. It signals you took the trouble. Get it checked by your child if you can; ring your daughter the morning you are writing the card and ask her how to spell his name on the inside. Accept that the joke you wrote in English will not land exactly the same way as you meant it. The rest of the card can be in yours. Keep both halves specific to him.

  • Happy birthday in your language and in mine, and in all the years of cooking you have done in between the two.
  • Happy birthday, Tomasz. I rang Mhairi this morning to check the spelling on the inside of the card and she laughed at me, which is fair.
  • You have built a life in a country that was not the one you started in, and you have made it look easier than it can possibly have been. Happy birthday.
  • Many happy returns. The phrase your grandmother in Krakow used to say, which Mhairi told me last summer, is one I have been trying to remember and I have not got there yet.
  • Happy birthday. The card has been written in English because my Polish is not where I want it to be yet. The intent is in both languages.
  • You have brought your mother's barszcz recipe up to Inverness and we have all tried it and we are all the better for it. Happy birthday.

For the son-in-law from a queer marriage

If your daughter married a woman or your son married a man, the gendered welcome-to-the-family lines in the shop do not apply at the most basic level. The role of son-in-law for a son's husband is being invented in real time by both sides; there are not many decades of grandparent-generation scripts for it. Write the card to the man. Use his name. Sign yours. The card does not have to do the work of explaining the family shape to him. He knows what shape it is. The card is just the birthday card.

  • Happy birthday, Tomasz. We do not always have the in-law words quite right for our family yet, and the card is from me, and that is the whole thing.
  • Happy birthday to the husband my son chose, who has been part of this household since the civil partnership, then the marriage, then the move to Inverness, then the small one.
  • You have been one of the steadiest people in this family from the year you joined it. Happy birthday.
  • Happy birthday from the mother-in-law of your husband, which is a slightly long way of saying I am very glad you landed in this family.
  • Happy birthday. The cards in the shop are not yet quite written for the two of you, so I wrote this one. With love.
  • The card-shop word is son-in-law and the word I actually use for you out loud is your name. That is the one on the front of the envelope. Happy birthday.

For the son-in-law you had a hard start with

This is the engagement you found out about in a text, the wedding day you almost did not get to, the silent year, the slow earning back. The birthday card has to live in that history without pretending it did not happen and without performing a reconciliation that has not actually arrived. Honesty in a small dose lands better than effort in a large one. Sometimes the single most useful sentence in this card is "I am still earning my way back to you." Sometimes it is one polite line and a signed name.

  • Happy birthday. We have had a hard run of years and the card is from me anyway, the same as every year.
  • Many happy returns. I am still working out who you are and I am still glad my daughter chose you. Both of those are true.
  • Happy birthday. There are conversations between us that are still to come, and the birthday card is not the place for them, and I wanted you to know I have not forgotten either part of that.
  • Happy birthday. I am sorry for the year of mine that made the first year of yours and Mhairi's harder than it needed to be. The card is short on purpose.
  • Many happy returns. We are in a better place than we were two years ago and you have done most of the work of getting us there.
  • Happy birthday. I do not love you the way I love my daughter, and that is the honest sentence, and I am glad she chose you, and that is also the honest one.
  • Happy birthday. From me, on the day, as ever. The longer conversation is for after the cake.

For the son-in-law you co-parent grandchildren with

When the birthday card is signed Granny and Grandad and the grandchildren have drawn something on the back of it in two different colours of felt-tip, the card is a slightly different shape from the one a childless couple sends. The card is partly from the kids. The card is partly thanking him for being a good dad to them, which is a thing he does not need you to say in three paragraphs but does benefit from hearing once a year in one specific sentence. Pick the specific thing. The bedtime he holds. The Saturday-morning ritual the kids will remember.

  • Happy birthday from Granny and Grandad, and Eilidh and Finlay who have drawn this themselves on the back in two different felt-tip colours.
  • You have been the dad who does the Saturday-morning swimming for the last five winters, and that is the kind of unglamorous regular thing the kids will remember when they are forty.
  • Happy birthday. The two small ones love you in a way that is not performance, and that is the entire job, and you have done it.
  • You have raised our grandchildren with our daughter in a way that has made us, the side they live forty miles away from, feel like we are part of it too. Happy birthday.
  • Happy birthday from the grandparents who get the call when one of them needs picking up from school, and who notice that the other call was made first. Thank you for the order.
  • Happy birthday. The bedtime story you do for Finlay in the voices, which we have heard on FaceTime exactly once when you did not know we were still on the line, is one of the small good things in this family.

For the year between you that has been hard

Sometimes the strain is recent and specific. A row at Christmas, the comment about how the kids are being raised, the fall-out about money, the row about your daughter's job. The birthday card cannot do the work that a sit-down at his kitchen table needs to do. The card can be quietly accurate, though. Short and plain and real, not the warm version of last year. Send it on the day, sign it from yourself, and let the real conversation happen on its own time.

  • Happy birthday. I hope the day is a good one for you.
  • Many happy returns. We will see you at the family Sunday lunch.
  • Happy birthday. We have had a strange year. The card is from me anyway.
  • Happy birthday. The card is short on purpose. The longer conversation is for after the cake.
  • Happy birthday. I am thinking of you today and I hope it is a kind one.

For the ex-son-in-law who is still the father of your grandchildren

If the marriage ended and you and he are still in each other's lives because the grandchildren are, this is one of the quietly truer cards you will sign all year. You are not his mother-in-law on paper. You are the grandmother of his children and he is, for that reason alone, family in a way the divorce did not undo. Sign the card from yourself. Skip any reference to the divorce. The card is about the day and about the man he has continued to be to the grandchildren.

  • Happy birthday. The marriage ended five years ago and I am still glad I get to send you this card.
  • You are the father of our grandchildren and one of the kindest men I know, and the paperwork from 2021 did not change either of those things. Happy birthday.
  • Happy birthday. We are not in-laws by certificate any more and we are family in every way that matters to me.
  • You have stayed a good father through the harder year of it, which has been the actual measure. Happy birthday.
  • Happy birthday to the man who has been a good dad to my grandchildren and a steady friend to me, regardless of the rest of it.

Funny birthday wishes for a son-in-law (gentle ones)

Son-in-law humour is the trap. The sitcom version has been running for fifty years and it is a tired thing. Skip the joke-shop register. The good lines come from whatever the running thing between you actually is. The repair he keeps making. The route he insists on. The team he supports. The thing he says at every Sunday lunch about the politics. The thing he refuses to admit about the football. If you do not have a running joke yet, do not invent one for the card.

  • Happy birthday to the son-in-law who has glued the back left leg of the kitchen stool three times now and has never once told my daughter I tried to fix it myself first.
  • You have driven the long way out of Inverness on the A82 to avoid one specific stretch of roadworks since the spring of 2022. Happy birthday, please keep doing it.
  • Happy birthday. Another year of you having a strong opinion about the way we have arranged the bookshelves in the front room.
  • You have brought the same Polish vodka up from Edinburgh to every Hogmanay since 2018 and the rest of us have stopped buying our own. Happy birthday.
  • Happy birthday to the man whose football team has not finished above mid-table since I have known him and who still rates them, on paper, ahead of the league leaders.
  • You have a position on Inverness traffic at the Longman roundabout that has been the same speech for four years. Happy birthday, please never stop.

Lines for a family group birthday card

A son-in-law's birthday is a natural group card in any family because the household has more sides than a single envelope. Your child who married him, the grandchildren, his own parents and siblings if the families are close, sometimes cousins. Group lines work best when they are short and unmistakably from one signer. He should read your line and know it is you without checking the signature. Coordinate it on the family chat, send the link, deliver on the morning.

  • From the mother-in-law you have been quietly mending the kitchen stool for since 2019: happy birthday.
  • Happy birthday from the father-in-law you have, against the odds, slowly taught to use the German wood glue you keep in the shed.
  • From the grandchild who knows you only as Daddy and would be very confused by any other name: happy birthday.
  • Happy birthday from the wife who chose you in 2018 and would choose you again on a regular Tuesday in May.
  • From your former mother-in-law, who is still very much your friend: happy birthday.

Turn it into a group card

A son-in-law's birthday is often one of the family cards that wants the most signers, because the household has more sides than one row of names will fit on. Your child who married him, the grandchildren, his own parents and siblings if the families are close, sometimes cousins, sometimes a few old friends from before the wedding. Each signer has a slightly different relationship to him, and the best version of the card lets each person write only the line they would actually write rather than a chorus of "happy birthday with love" repeating down the page. A group birthday card online handles the logistics without anybody having to ferry a paper card across two countries: one link to the family chat, everyone signs on their own time, the card lands on the morning of. You can create a card online in a couple of minutes, set the delivery for the morning of his birthday, and use an old photograph for the cover (the wedding-morning picture of him and your daughter on the registry-office steps, or the one from the first grandchild's christening, both work). If you would rather send something quiet from just yourself, a free online birthday card goes in seconds, and for any family occasion that wants the whole household at once, an online group together card is the right shape.

For the private paragraph card from you alone, the full guide to what to write in a birthday card has the four-part structure these lines are built on. The wishes for your daughter set is the obvious other half of this one if her birthday and his land in the same month, the wishes for father-in-law piece is the sideways neighbour for the in-law card you might be writing in the opposite direction, and the wishes for sister-in-law guide is the third one in the same family if her sister's birthday is on the same Sunday lunch.

The stool is back under the kitchen window with all three legs solid as of last October. Mhairi rang me on the Sunday Tomasz dropped it back and asked, casually, whether the GCSE woodwork teacher who taught her the class in 2009 had ever liked her. I told her, also casually, that I had no idea. The teacher had been a woman called Mrs Lockie who taught woodwork in a school in the south of the city, and Mhairi had got a B for the stool, and I had thought at the time that the B was hard on her because the stool worked. The woodwork teacher retired the next summer and we never heard about her again. The leg has come loose three times in seventeen years and has been glued back twice by the man my daughter married. The card I wrote him this year was about the stool, not about her. Write him a card. Mention the small thing only the two of you know.
