22: Never talk to a man in a bathroom unless you are on equal footing: i.e., both urinating, both waiting in line, etc. For all other situations, an almost imperceptible nod is all the conversation you need.
Ah, yes.
Two incidents stand out...
One was at the corporate dining room my sister and I did the catering for fifteen years ago. One of the employees there was this friendly young guy who never made that significant an impression on me, just one of the people working there, in other words. I was doing my business at the urinal in the men's room, and he came in, and went to the urinal next to mine, gave me a friendly hello, and put his hand gently on my shoulder for just an instant. My whole being went cold...I considered it a pass. He felt the chill, and he went, "oh, God, I'm sorry..."
From that time on, he became very nervous around me, very concilliatory.
Another time was when I was working at a corporation then owned by a billionaire who has since gone into politics. As I was doing the aforementioned business in the men's room, one of my colleagues came in, and whilst we were both peeing, he wanted to expound on the never-ending right wing vomit that continuously obsessed him. What kind of asshole wants to start a political discussion while you're both peeing in a urinal? I said to him, "get the fuck away from me, and don't talk to me again today." He couldn't understand why I was being so unfriendly...
