talking to myself

You know you're a stay at home Mom with no one to talk to when you start having a conversation with yourself - AND YOU HAVE A GUEST OVER.
Today my friend came over and we were talking on the couch when I started to have a conversation with myself. I can't remember what it was about, but I think I was trying to remember something correctly so I was asking myself "No. That can't be it. Can it? I don't know...maybe." etc. etc. I shortly realized what I was doing and pointed it out to her. She laughed and said she had just noticed the same thing.
Oh well.
