Have you been to a school cafeteria lately?
We don't know the backround on why this rule was put in place but we do know that this child was not following the rules three times and was punished.
As I said, if the child followed the rules and the parent fought at that point, I would have no problem. Instead another lawsuit because a child did not follow the rules and daddy doesn't like it. Our taxes go up in lawyers fees and the NEA screams they need more money.
Children act only the way we expect them to. If we expect them to follow the rules (even the stupid ones) and work to change them, they will act that way.
I shudder to think what these folks would say about a rule in a grammer school I went to. There was a line painted down the hallway and we "shudder" had to walk on the right side only. If we crossed the line we would have to stay after. And if we were exiting as a class, we had to form a line.
Now that I think about it, these tyrants in my old school should be shot.
