I too tend to plug my ears if there is someone else in the washroom. It`s weird.
I don`t really have a problem with going to them now, but when I was in high school, I don`t think I ever used one at school, ever. But the problem with that is that I had to go really bad as soon as I stepped into my driveway.
What I find is worse than this, though, is the inevitable bathroom breaks that must be taken during the day by females of a certain age, during a certain time. I won`t go into detail of course. But public washrooms and that are just a pain in the butt!!
Ever since I found out what is inside the men`s bathrooms... I`ve always wondered how they can do it. I couldn`t if I was a guy. TOO EMBARRASSING!
P. S. One time when I was at a social in elementary school, and I went to the bathroom, these kids looked over the top of the stall at me!!! Now that is not pleasant!!
