Belated birthday letter for your sister

Dear Sam,

By now you have probably told at least three people that your sibling forgot your birthday. That is fair. I would have done the same. I am sorry, and I fully accept the teasing that is coming my way at the next family dinner.

In my defense, I have no defense. I simply looked up from my week and realized your birthday had come and gone, and that I had been the one person too scattered to notice. Mom would be so disappointed. Please do not tell her.

Here is my plan to make it right. One sister day, entirely on me. Breakfast at that cafe you like, a walk, a long lunch and all the catching up we never seem to have time for. You can choose the movie afterward, even if it is one of your terrible ones.

The letter

Dear {firstname},

By now you have probably told at least three people that your sibling forgot your birthday. That is fair. I would have done the same. I am sorry, and I fully accept the teasing that is coming my way at the next family dinner.

In my defense, I have no defense. I simply looked up from my week and realized your birthday had come and gone, and that I had been the one person too scattered to notice. Mom would be so disappointed. Please do not tell her.

Here is my plan to make it right. One sister day, entirely on me. Breakfast at that cafe you like, a walk, a long lunch and all the catching up we never seem to have time for. You can choose the movie afterward, even if it is one of your terrible ones.

Under all the jokes, I want you to know how much I love you. You have always been the best part of growing up in our house. Happy belated birthday, sis.

Your very sorry, very loving sibling,

Make it personal

  1. 1

    Beat her to it. Your sister will point out that you forgot. Say it first, with a short apology or a joke at your own expense.

  2. 2

    Remind her of your history. The shared bedroom, the borrowed clothes, the road trips in the back seat. A memory shows she is never far from your mind.

  3. 3

    Make a plan together. Brunch, a movie night or a sister day out. Give her something to look forward to.
