I didn’t go to Catholic school, but I did attend a Catholic university for undergrad and graduate school, and taught in two different catholic schools before entering into a public school district.
Probably the weirdest thing I saw, was the anal retentiveness about boys facial hair. One school I was at would make boys shave in the mornings in the Dean’s office and give them detention for having a little bit of scruff. They would frequently go on the morning announcements and remind boys about the rules, claiming that it interfered with their education and wasn’t an indication of cleanliness. One day- and it still makes me laugh- they made the announcement, and a boy dropped to his knees in the hallway, looked up and shouted, “JESUS HAD A BEARD!”
Three teachers rushed at him to get him to knock it off, and I had to duck into my classroom because I started laughing so hard I was in tears. True. Jesus *IS* always depicted with a beard!
