I'm currently not taken, but my best friend is a boy, so we're close.
He always says stuff like, "At the other high schools, boys can't hug girls in the hallway!" And then he comes over and gives me a sloppy hug which makes me drop my books. It really is hilarious, and he does it constantly. I've known him since he was six, so I don't really care if he does it or anything, but sometimes I have to bonk him on the head to make him stop making me drop my books.
