I had a bunch of nuns like the penguin between 3rd grade and senior in H.S.
In and out of school...the out of school nuns were the worse.
You must have went through grade school before me, I went late 60’s to mid 70’s, the nuns mellowed out a bit by then but there were still enough bruisers roaming the halls to do some damage. Now the Christian Brothers in High School were another story.
