1. Happy birthday to my sister! Remember when we fought over the last slice of pizza? Spoiler: I still would. Enjoy your day… and maybe hide the snacks.
2. To my sister: Another year older, another year of me pretending you’re the “mature one.” Happy birthday—let’s keep the chaos going!
3. Happy birthday! They say siblings are your first friends… or first enemies. Lucky for you, I’m both. Hope your day’s as fun as our childhood pranks (sorry about the hair gel incident).
4. My sister’s birthday = excuse to eat cake, make fun of her old photos, and remind her I’m still the favorite. Enjoy your day, loser—love you!
5. Happy birthday! You’re not getting older, you’re just… *more experienced* at stealing my hoodies. Thanks for being my partner in crime (and my personal closet).
6. To my sister: I searched for “funny birthday quotes” but figured I’d just write the truth—you’re old, but at least you’re not as old as Mom. Happy bday!
7. Happy birthday! Remember when we told Mom the dog ate your homework? Yeah, that was me. Oops. Hope your day’s better than that lie (it can’t be worse).
8. My sister: The only person who can borrow my makeup, eat my snacks, and still make me laugh. Happy birthday—don’t push your luck with the snacks today.
9. Happy birthday! They say age is just a number. For you, that number’s “way higher than mine.” Love you, even if you’re basically a fossil now.
10. To my sister: Another year, another chance to remind you that I was the better kid (sorry, not sorry). Happy birthday—let’s celebrate like we’re still 10 (no curfew this time!).
11. Happy birthday! You’re the reason I know how to lie (thanks for covering for me with Dad) and the reason I have no snacks left. Enjoy your day—you earned it (sort of).
12. My sister’s birthday: Time to eat, drink, and ask her why she still has that cringey middle school diary. Happy bday—don’t worry, I won’t read it… out loud.
13. Happy birthday! I hope your day is as great as you think you are. (Spoiler: It’ll be better, because I’m here.) Love you, drama queen!
14. To my sister: Another year older, another year of me hearing “when are you gonna grow up?” (Spoiler: Blame you—you taught me to be this way.) Happy birthday!
15. Happy birthday! You’re the only person who can annoy me for 5 minutes and make me laugh for 10. Enjoy your day… and maybe stop stealing my coffee.
16. My sister: The one who knows all my secrets, all my flaws, and still chooses to hang out with me. Happy birthday—let’s keep each other’s secrets (and steal each other’s food).
17. Happy birthday! Remember when we tried to dye each other’s hair and ended up with green streaks? Good times. Hope your day’s as memorable (but less messy).
18. To my sister: I don’t need a fancy quote—just wanna say: happy birthday, stop hogging the remote, and I’m still faster than you. Love you!
19. Happy birthday! You’re not old—you’re just “vintage.” Like wine, but with more bad jokes and more stealing my sweatpants. Enjoy your day!
20. My sister’s birthday = my excuse to be nice… for 5 minutes. Then it’s back to teasing you about your terrible taste in music. Happy bday—love you, dork!
