There’d have been a big problem if anyone at a school laid a hand on my kids.
I won't tolerate a teacher, or any other school employee, so much as verbally reprimanding my children.
The difference I bet is your kids don't act like little @ssholes at school. Some of these little chits need a good whack on the arse. I bet that kid has her act together from now on. Principal gets a gold star from me!
