My sister is pregnant.
I have friends who are getting married.
I live on my own.
I have a real, 9-5 job.
I have my own health insurance.
I can buy booze without feeling silly.
I'm planning my first vacation ever on my own, and I'm using paid vacation time to take it.
But the thing that pretty much everyone my age has that I do not (regardless of all the other stuff) is a credit card. And I just applied for one. And I was accepted. I guess I'm officially an adult now. And it's weird.
