Hey Michael, I too talk to myself all the time. I have done this since i was a wee kid. I use to get slagged by my family for this. So i invented an imaginary friend called "Walter" Even as i write this i am talking to myself. I do not understand why i do this, but i do. I suppose its a habit i have never grown out of. It is good to feel like someone is actually willing to listen to you. I come from a family where we do speak and conversations flow all the time. But i guess as you said its an insecure thing. God knows why though. I talk about everything and anything to myself. I probably sound like a nutter now sorry guys
