I talk to myself when I'm alone. Not all the time but on occasion and a lot of times when I smoke. Then there's the times I accidentally talk to myself when I'm not so alone like today when I'm leaving the corner store into my car, I was just talking to myself and someone was looking at me like "What the hell...".

To be honest, I think talking to oneself is just another one of those things that's perfectly natural but has a strange stigma to it.
