Finally 21, and it feels amazing.
Cheers to being 21!
My twenty-first year. Let's go.
21, and I finally get it. Kind of.
Officially 21. Legally celebrating.
Twenty-one going on twelve.
21 and fearless.
21 and in my prime.
21 is going to be a good year.
Blew out 21 candles and nearly set off the smoke alarm.
21 and ready for whatever comes.
Twenty-one and having fun.
Grown up, sort of.
21 and making memories.
