Birthday letter for your brother

Dear Sam,

Happy birthday, big brother. I have started this letter about six times, because it turns out it's hard to fit a whole lifetime of gratitude into a few paragraphs. But here goes.

When we were kids, I thought you were invincible. You knew how to climb out the bedroom window, how to talk your way out of trouble and how to make me laugh until milk came out of my nose. I followed you everywhere, and you let me, even when it wasn't cool to have your little sibling tagging along.

As we've grown up, what I admire most is not how tough you are but how much you care. You remember the things that matter to people. You call when someone is struggling. You show up with a toolbox, a pizza or just your company, depending on what's needed. You have been that person for me more times than I can count.

The letter

Dear {firstname},

Happy birthday, big brother. I have started this letter about six times, because it turns out it's hard to fit a whole lifetime of gratitude into a few paragraphs. But here goes.

When we were kids, I thought you were invincible. You knew how to climb out the bedroom window, how to talk your way out of trouble and how to make me laugh until milk came out of my nose. I followed you everywhere, and you let me, even when it wasn't cool to have your little sibling tagging along.

As we've grown up, what I admire most is not how tough you are but how much you care. You remember the things that matter to people. You call when someone is struggling. You show up with a toolbox, a pizza or just your company, depending on what's needed. You have been that person for me more times than I can count.

So on your birthday, I want to say it plainly: thank you. I'm proud to be your sibling, and I'm lucky to have you in my corner. Enjoy your day. You've earned a good one.

With love and respect,

Make it personal

  1. 1

    Pick one memory. The treehouse that fell down, the haircut you gave him, the long drives. Specific beats generic.

  2. 2

    Mix the joke with the real thing. Brothers often skip the soft stuff. One sincere line after the joke means a lot.

  3. 3

    Choose the channel. A quick text or group chat for a one-liner, a card or letter for a milestone.
