....do you talk to yourself? Or by yourself? Or in any context where you are the only person in the room/area? Or where you know no body can hear you?

Why?

I don't think I do this much. I think I do it when I'm really frustrated thinking about a problem in school and I'm trying to figure out an answer. So I guess it's a sort of stress relief for me, it's about the only times I can think that it's happened to me.
