it sounds like the bully wasn't doing much physical bullying. but average joe fuckface thinks any contact at all = i get to break your face.
In real adult life, the bully gets some little misdemeanor ding, maybe. The violent person gets a battery charge, the bully's hospital bill, anger management classes, community service, etc.
but average joe fuckface also thinks he should get to revert to the code of hammurabi whenever he feels like it because he can't see outside his little bubble, so he would spite the courts for that ruling too.
