Like Jeffery I talk to myself. At work they are used to it. As for public restrooms, I figure strangers will think I’m a lunatic and leave me alone.
Within a reasonable length of time there will be an article that, among other things, describes bathroom etiquette in prison. (Update: Click here and scroll down to “House Rules — TMI alert!”) I’ll keep you posted. It won’t be written by me but I’m involved. As you can imagine, there are similarities as well as important differences. For example, I doubt if many people work where there is a designated jacking-off stall.
