This happens to me too. Happened about an hour or so ago in fact. Changed in to this sullen guy who 'to me' is kind of a jerk but, he/it has no name. It comes and goes. Now I'm me again. The original I mean and I don't even know when I changed back. I really would like to know just how many there are in here with me and for them all to have names. I think that it would be easier to keep track of things that way.
