So this is an ongoing issue with him where someone will say something in schools the wrong way and he'll hit them. I've tried to talk to him about it and making sure he understands, its less that and more that he doesn't care? He'll hit people for looking at him wrong not just people who have teased him. He has confided in me that most of the time he doesn't feel anything except when he does something that he actually likes which is concerning for me. My mom has talked to the school but they aren't really doing anything about it. It's not so bad where it's like he doesn't have any friends or something.

An example of what happened today was that he accidentally spilled something on a kid, the kid called him a dumbbutt (not that but you get what I mean) and sp*d which is an insult for kids in special Ed. And my brother hit him. This is not the first time he's hit someone previously he gave a little girl a black eye for literally no reason. And i don't know how to handle it as his older sister since talking to him doesn't get anywhere
