Is it normal my brother acts like such an asshole at school?
My brother is 16, and I'm roughly 2 and a half years older than him. We both go to the same school, and we have a normal brother sister relationship at home, and we've both got each other's backs when it comes to it. But at school he is SO nasty, and a completely different person. When I walk by him and his friends and one of them says something like 'Hey, isn't that your sister?' and he'd say something like 'Yeah, I drew the short straw didn't I?' and then he'd look around at all the girls in the group and wink at them or something. He also rides the bus with a few good friends of mine, and they tell me that he teases them or calls them 'his sister's people' which isn't meant to be a good thing (he's usually fine with them if they come around to our house) and once pushed a younger kid into the little toilets that they have when they get picked up on the travel coach and locked him in, and when the kid came out crying, he was laughing his head off. He's also told numerous lies about everyone in our family including me to make him and us look better than we are. It's truly horrible for me to see him like this.
It may be normal in some respects but if I wrote out everything he's done this would be much longer...IIN?
