There are some helpful hints for all of us in the "Bathroom Survival Guide", and I don't think we shy ones are being singled out at all.
I remember, with horror, when I was having a conversation with my boss (we're both women) that continued into the ladies room. Women can often talk and pee simultaneously, even though it is weird. Well, my boss proceeds to take a big dump, all the while discussing our monthly performance numbers. Awwwwwgh! A tiny part of me was envious that she was so uninhibited, but I was mostly grossed out and never regained any respect for her.
These rules would have helped her understand my discomfort, I'm sure.
Is a "shameless shitter" any more normal then a shy one?
