I laugh at immature jokes, I stay up 'til 3 in the morning playing video games, and I eat cereal for supper. I still feel like a teenager, but somewhere along the line, me being an adult slipped right in there. I pay bills, I budget my money, I work a full-time job, I have to clean my own house.
Seriously, why wasn't there a class for this? I mean, I picked it up over time (after overdue bills and piles of dishes higher than myself), but damn. This is an odd experience. Not that I regret it, because I can do the various things I said in the first sentence without my parents murdering me. Drive wherever I want. Decorate my house with doilies if I really wanted to (I don't want to). It's pretty chill.
