For example, I often talk to myself. And by that I mean as in a back and forth conversation. Usually it’s under my breath but sometimes it’s much more audible. It’s not so bad when I’m in the car since I can pass that off as if I’m talking on some Bluetooth device, but I’ve been caught a few times on my mail route. I usually try to make it appear that I’m singing but most customers know better. It’s bad enough when I get the odd spider web in the face and they see me swiping at something invisible on my head. So they probably think I’m a nutter. They may be right.
