I talk out loud to myself all of the time. I even do so in public, sometimes. What I say seems interesting to me, but maybe it wouldn’t to others. Often I just say odd-ball random things, or repeat phrases or make odd noises. Just yesterday, my hubby came into the bedroom from his office asking who I was talking to. I just told him not to worry and that I was talking to myself and to “Go back into your office and leave me be!” And only 20 minutes ago, I was in his office with him and started to talk to myself again. He became annoyed and told me to be quiet (he was working), so I just went to my bedroom and shut the door, and began talking to myself again, happily.
