Proud, in plain words

Many grandsons grow up hearing "look how tall you are" from every relative. What they rarely hear is a grandparent saying, simply, that they're proud of the person. A birthday card is a good place to say it.

Try:

  1. 1.Happy birthday, with his name.
  2. 2.One thing he did or one quality you've noticed: how he helps his little sister, how hard he trained, how he always says thank you.
  3. 3.A plan: fishing, a ball game, his favorite meal at your house.

For example: "Happy 11th birthday, Max. You worked so hard at baseball this year, and you were a good sport even when your team lost. Grandpa and I are very proud. Burgers at our place on Saturday?"

Writing for different ages

  • Little boys: short, excited sentences about what he loves right now. Expect it to be read aloud.
  • Teenagers: keep it short and don't embarrass him. One line of pride, plus a plan or a little money, goes a long way.
  • Grown grandsons: write to him as a man you respect. Mention his work, his family, a choice he made. Tell him a story he's too young to remember.

Doing something together

For many grandsons, the best present is time with a grandparent who's interested in what they like. Put a plan in the card: a ball game, a trip to the hardware store, a card game, his favorite meal at your house. Then keep it.

Money and the card

Teenagers often look for the money first. That's fine. Write your one real sentence above it, so it gets read on the way.

What to leave out

  • Questions about girlfriends, grades or his weight.
  • Comparisons with his brothers, sisters or cousins.
  • Advice. Save it for when he asks.

Frequently asked questions

What do grandparents write in a grandson's birthday card?
His name, one thing you're proud of, and a plan to see him. For a little boy, keep it short and excited; a parent will usually read it to him.
What should I write to a teenage grandson?
Something short that doesn't embarrass him: "Happy birthday. We're proud of you. Burgers at our place soon?" Teenage grandsons don't always say much back, but the message still lands.
What can I write to a grown grandson?
Tell him a story from when he was small, and tell him what kind of man you see now. A plain sentence of pride from a grandparent is something many men keep.

Never miss their next birthday

A grandson may not say much about the card, but he'll often keep it. Write one line about the young man you see growing up, and save his birthday so Greetigo emails you the day before.

Save the date and Greetigo emails you before it. Then pick a free template or, on Plus and Premium, start from an AI-written draft. Send it by email from Greetigo, or copy it into WhatsApp, a text or your own email app. It works in any browser.
