First of all, sorry for my English, my native language is Italian. 

Today at school the teacher gave us an IT test, everyone scored poorly. I was complaining with a friend about the fact that the teacher lowered our score for a mistake that even other people made, without getting their score lowered. 

This guy (M 16) not involved in the conversation started mocking me for my bad mark. I ignored him but after a while I pointed out that he got a better mark because he has a certificate for learning disability (that's a fact). He said that this wasn't true, then we argued for a while, until that guy started to threat me saying that he would punch me and other bullshit. I laughed because he was ridiculous, then the teacher calmed us down.


I feel guilty because after he insulted me i called him a retard, AITA?
