Well, I wasn't hit, but my 6th-grade-private-school principal once put me in isolation.
A girl accused me of throwing a ball at her on purpose. (It was in P.E. during basketball.) My principal believed her since her mommy was a teacher
So, I was placed in In-school suspension. This meant that my parents THOUGHT I was being watched while sitting in the office.
But, in reality, they placed me in a storage closet for three days straight!
It really wasn't that bad, because I slipped out and went to the bathroom whenever I pleased. No one came to check on me, so I slept a lot.
