Happy birthday, sis. We don't say it enough, so let me say it now: you are extraordinary. This is embarrassing for both of us. Let's never speak of it again.

Happy birthday, sis. You have known me through every version of myself , the embarrassing ones, the brave ones, the ones I'm still trying to figure out. And somehow you keep showing up like none of it has changed the way you love me. That kind of steady is rare. That kind of steady is you. Happy birthday, my first and forever friend.

Happy birthday, sis! You're the only person I can fight with at 9am, laugh with at noon, and overshare with at midnight — all without consequences. Don't ever change. (Okay, maybe the borrowing-my-clothes part.)

Thirty, sis. You officially no longer have to explain your decisions to anyone. You're too old for that. You're also too old for a lot of things you're going to do anyway this year, and I am not here to stop you. I'm here to hear about it later, judge gently, and go back for more. Happy 30th. Let's make it worth remembering.

Happy birthday, sis. I would say you're the better one of us, but it would make you insufferable. So I'll just say you're excellent, in a very close second-place sort of way.

Happy birthday, sis. We grew up in the same house. We survived the same chaos. The fact that both of us turned out functional is a greater achievement than anyone gives us credit for.
