MANY Many decades ago, I went to a Parochial school where the nuns ran it like the INQUISITION!!! If a student had to go potty, they were told to HOLD it until recess or break. I remember many times when, especially the girls, would beg to go and be denied by the nuns. Shortly later, the girl would burst into tears as the floor around her seat was suddenly flooded with PISS!!!! Now, THAT is embarrassment!!!! Of course, there was lots of chuckling and teasing by the other students. I always made sure I had the bladder FULLY EMPTY before class started!!
