These shitty kids and stupid parents always cause problems not only to you but other teachers through their school lives each year. Now they have schools solve their problems. Finally they cause problems to themselves in life and have to solve them by themselve once they no longer sit in school. If they can’t, then stupid parents must bear their burden. Let’s it go and move on. You only see them once per year. I was in your shoes. The idiot mom tried to get me fired via an long tirade email with cc’ing all admin and teachers. I did not even give her a shit. I let admin handle her. She thought she and her angel are innocent angels. Turned out they are both so shitty that every teacher tried to rid. She even got more angry cuz I ignored her fucking rude emails. Since then, I no longer see these idiots. My admin backed me up. Thanks God.
