I hate washroom talk. A "Hi" is okay but that is where I draw the line. I especially do not like side by side urinal chatter in the washroom. Last night though I had my worst washroom talk experience. I was in Sneaky Dee's washroom, washing my hands (of course) and some old guy came up to the sink and said "I don't even know we wash our hands. My dick is the cleanest part of my body."
I looked at him, my eyebrows lowered. I turned around and walked straight out.
