Yes, all the time if i am alone. The only time i talk to myself out loud is if i am 100% alone and only if a am ranting...F* and SH** and all that come out. Actually, that isn't really talking to myself, i don't think. It is the converstions i WISH i could have with someone who p*sses me off, that i haven't been able to say these things to her face.
