I talk to myself too. I didn't know it was such a problem till people at college noticed. I would tell them I was studying. Apparently I do it all the time. When I was home I couldn't believe my dad told me, "You should walk around with a cell phone to your ear. That way it will look like you're talking to someone...else, and arn't just some crazy person."

I never knew other people did this. Do the rest of you? Sorry to sort of thread jack, but I figure since we all are talking about being lonely...
