As both someone who was bullied in high school in almost this exact scenario, as well as someone who has dealt with anger issues in life, I certainly understand OP’s reaction. As a father I would understand, but I’d also want my child to strive to measure her response. Life is going to be fill with pain and annoyance and having violence be your go-to solution for that is going to a life of misery.

Yeah. If I punched someone at work in the face for being an ass and laughing at me, I’d get fired at best and charged with battery at worst.

Violence isn’t an appropriate response to someone being annoying
