i would like to thank whoever invented the hands free phone kits, because of them it looks like most people walking down the street are talking to themselves, so i do not stick out like a sore thumb when my mind wanders and i really am talking to myself!!!! i find my conversations are often ones i have with me, i always get the reply i was looking for!
I talk to myself out loud sometimes just to hear a human voice that is not through electronics. i have on occasion made myself jump when i am home alone and my mind has wandered and i suddenly say something out loud!
