I must say, the celebration we had for your birthday was quite a spectacle. The amount of food and drinks we consumed was truly a sight to see.

Thank You Letter For Cousin Sister’S Birthday Sample 2

Dear Cousin Sister,

I just wanted to take a minute to say thank you for having a birthday. Without it, we wouldn’t have had the opportunity to eat cake and embarrass ourselves on the dance floor. Plus, your birthday parties are always the perfect excuse to get the family together and remind us why we only see each other once a year.

I also want to thank you for aging gracefully. You make it look easy. I mean, some people get one wrinkle and they act like the world is ending – but not you. You embrace each new year like it’s a gift (even if that gift comes with a few extra gray hairs).

Speaking of gifts, I hope you liked the toaster I got you. I mean, I know it’s not the most exciting gift in the world, but who doesn’t love toast? You can use it to make breakfast, lunch, and dinner. Actually, now that I think about it, maybe I should have gotten you a cookbook too…

Anyway, thank you for being the best cousin sister a person could ask for. You’re always there for me when I need advice (even if that advice is just “drink more water”).

Happy birthday, and here’s to another year of making memories – and hopefully not breaking any hips in the process. Love you!

Sincerely,

Your favorite cousin (don’t tell the others)
