It's a technological breakthrough! It's finally okay to talk to yourself--out loud. Some have been doing it for years and they probably feel a bit self-conscious about it if others see or hear them. I've caught a few by surprise myself. But, hey, now it is just plain okay to do it. Matter of fact, I see people doing it everywhere I go--in the supermarket, airport, the mall, the cleaners, you name it. They are doing it everywhere.
Well. . . not quite. They are talking into their barely visible bluetooth unit and it looks just like they are talking to themselves out loud. You've probably even said, "what did you say?" to someone, just then seeing they are really not talking to you.
But, here's the good news about this technology: now you can talk to yourself out loud and no one will be the wiser. You can even get animated and make it a real talk instead of just chit-chat. Go for it. Now it's legal. Even I'm doing it now. It's fun too.
