personally i don't think it is bad to be the serious one. i think if you want certain things, you shouldn't settle for anything else. sure, some things can be corrected over time, but if you don't have someone who is on your level, then you're wasting time. someone out there is willing to give you just what you want.
as far as the hair, i'm going to disagree with everyone else. i love your hair the way it is. i think if you wanted to add red into it, that would be super hot, but not the whole thing! anyway, could to see you back!
