Ffs, when I was at school the teachers do that when we misbehaved. They had to do something when they abolished corporal punishment. Parents who think their kids are precious, sensitive little poppets who are beyond being punished for acting out of line are part of the reason society is going down the pan.
Kids who cause trouble or disturbances should simply be thrown out of class for the rest of the period. The other kids are not there to watch little jimmy's imbecile antics. Maybe they actually want to learn something.
But of course we can't do that because it would hurt poor little jimmy's sensitive feelings and scar him for life. So instead the rest of the class has to endure little jimmy's idiotic outbursts.
You said it. They don't want their snowflake punished, EVER, but you know they breathe a sigh of relief every morning when that kid heads off to school and the house is "quiet at last!" Because they aren't disciplining them at home either.
