I also have this really weird thing about leveling in video games. Everyone MUST be equal. Like, I'll kill the other characters and level only the lower ones until they're all on the same level. I'm a bit anal about that, in fact. I don't know why O.O
I do that almost exact same thing. When level grinding, I try to make sure all of my characters are exactly the same level, and if one levels up, I try to balance it out again.
Another thing is that I say sorry too much, and when its not needed, or not my fault. For example, someone says, "Man, I just failed that test." I'd say, "Oh, I'm sorry" for really no reason. And then they look at me all weird.
