Of course. I don't really know what they are though - it's just mood and situation dependent.

My weirdest one is me going quiet. If you know me well enough you know that I'm depressed when I can't think of words.

Mostly I just bundle along. But if it's a new situation, I'm overly talkative; if it's a sad discussion I know when to shut up; that kind of thing. Nothing big. Trouble for me comes when trying to figure out which part is the real me...but these days I've started to think that I'm the sum of the parts, rather than just one part.
