What nonsense!
Does he not listen? Did he not hard you? If he had issues, he should fix them before coming to the public space. You can't deal with kids with that kind of attitude.
This one really pissed me off. Guy, e pain me!!

My further maths teacher in high school also had a temper. He used whatever object that was close by to whip students. One day, he almost hit one with an extinguisher.

Better yet, they should have to deal with these issues first.
