1. Happy Birthday, sister!! As you get older, I hope you always know I have your back. You can call me anytime (I mean, if I don’t answer, don't call BACK to BACK to BACK! Haha!). I love you so dang much, even when you are being a turd.
2. A sister knows you inside out and they know all your secrets… You better not blab to anyone cause I know all your secrets too! Okay, let’s call it a truce. Love you, sis. Wishing you the happiest birthday!
3. Here's to many more years of dealing with our kooky family together.
4. You're the cheerleader I never knew I needed.
5. You're the peanut butter to my jelly. The sanity to my crazy. The gin to my tonic.
6. No matter how old I get, I’ll still always be younger than YOU, you old fogey!
7. Happy birthday, little sis! Thanks for reminding me how old I am… ugh! Now give me some of that cake so I can drown my sorrows!
8. Happy Birthday, sister! You better go check if you grew! I’m so glad the aliens sent you to earth all those years ago to be my sister. I hope you have a fun birthday! We love you!
9. Your sibs have talked, and we agree—you need to stop outshining us! 😂
10. Thanks for being the best gossip in the fam. Childhood would have been so boring without you!
11. Happy Birthday, sister! Can’t believe how old we’re getting! Love you!
12. You paved the way so I could bushwhack through the woods!
13. Another year older, can't say another year wiser. Happiest of birthdays to my partner in crime!
14. Even if you weren't my only sister you'd still be my favorite. Happy birthday!
15. Have the best night celebrating and as always, call me if you need anything.
16. Thank you for all the cute clothes I stole from you over the years! 😂
17. No matter how old you get, I'll always be younger. Happy birthday, grandma!
18. You know you’re old when you look forward to bed at 9pm and make plans with friends knowing you’ll just cancel them later… Welcome to sweet old age, sis! Happy birthday
19. Still not sure who's the favorite kid, but we can set that aside for today. Happy birthday, sissy!
20. We fought as children so we could bicker as adults. I wouldn't have it any other way.
