I couldn’t imagine being a teenaged girl and going in to use the facilities and finding this nut case in there. Are they insensitive if they turn and leave? I hope the girls all have good, strong bladders.
When I was in high school, I learned to go all day without using the bathroom because there were so many students smoking and using drugs that you couldn't even get to the toilet.
My family hated car trips with me for many years.
