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. 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. Nobody else in the world can call me out like you can, and somehow when you do it I feel less crazy, not more. You're my calibration tool. Thank you.

Twenty-one, sis. The world is opening up , go meet it on your terms, the way you've always done. Just remember to call home sometimes. Happy 21st.

Forty looks unfairly good on you, sis. May this decade hand you back every brave, generous thing you've poured into the rest of us.

Thirty, sis — and you wear it like you wear everything else: confidently, beautifully, on your own terms. Here's to a decade of bigger plans, deeper friendships, and exactly the life you've been building toward. Happy 30th.

Happy birthday, sis. The older I get, the more I realize that everything I know about surviving difficult people I learned from you. You were the training.

Happy birthday, sis. You were my first friend, and you'll be my last call. The world made us family, but I'd have chosen you anyway.

Happy birthday, sis. Of all the people I could have grown up beside, the universe gave me you. The first person who knew every weird thing about me. The first person who never made me feel weird about any of it. I'll never stop being grateful for the assignment , for the random, holy accident of growing up beside you. Happy birthday, my first and forever friend.
