Yes, you are all crazy. But I am too, so it's all right.

But to answer the question...I talk to myself all the time too. I'm even known to argue with myself. O_o It may sound completely nuts, but a lot of times it helps me to work through my problems to sit down and have a nice long conversation with myself. Maybe I'm the only semi-intelligent person I have to talk to. Or, maybe I'm just lonely. Who knows.
