I don't know what it is, but lately I've been meeting a lot more people around my age. This is a generally awesome thing because it's nice to have people to talk to that aren't 5 years younger than me all the time. I'm not saying I dislike talking to my younger friends, but it's definitely nice talking to people I have a lot more in common with.
I dunno why though, it's like everyone I meet lately is around my age or a bit older. >:U
