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.

Thirty, sis , and somehow you're more yourself than ever, which is the best thing a decade can do for a person. Here's to bigger plans, deeper friendships, and a year that finally pays back even a little of what you give everyone else. I'm proud of you. I'm lucky to know you. Happy 30th.

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. 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. 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. Some part of me was already learning how to love by watching you. The rest of me is still trying to catch up.

Forty, sis. The decade where you stop pretending to like things you don't like, stop going to events you don't want to go to, and start charging what you're worth. It's the most powerful decade there is and it looks incredible on you. Don't waste a single year of it. Happy 40th.
