A friend of mine (Headteacher of a RC primary school) once told me about his first week as a HT.
There was a mass assembly (as in religious mass) and he was standing at the back, overseeing things as the kids got settled.
He had been told about one lad called Neil, who was particularly troublesome.
As he watched, he saw Neil pulling the hair of a girl in front of him.
He shouted out "Neil!!"
Guess what happened in the assembly hall of the Roman Catholic primary school?
Yip, all the kids dropped to their knees, ready for prayers
