I was around them when I was a kid. They had detention, and the lady in charge of detention was a Miss Lynch, who would make Helen Thomas look like a super model, and she was hell on wheels when she was in a good mood WITHOUT using corporal punishment. A few sessions with Miss Lynch yelling in your face like a drill sergeant, and that was the last time you ever came to school late, fought, or talked without raising your hand. Tantrums? Not unless you wanted to see Miss Lynch.
And you can’t do that in public schools today either
And by the way.... times have changed since you were in elementary school
