I'm a grown up.
Here are just some of the things that make it true.
1. I have a joint checking account with someone
2. My body hurts a lot more than it used to
3. I don't like fast food or cartoons anymore (well, not as much as I used to)
4. The weekends mean sweatpants and sleeping more instead of party clothes and staying out late.
5. I care about property taxes
6. I own furniture that I bought new
7. I have a guest room
8. My dog is older than the Titanic (the movie)
9. My niece is 16, has a job, and a nose ring.
10. I dye my hair to cover gray.
