[There's a pause before, finally, a frustrated sigh]
Look, I know guys like him back home. They have a problem, they take it out on other people. Sometimes they pick one just one guy and take everything out on him.
A friend of mine ended up being one of those guys. They picked on him and he just kept taking it and taking it. They would break his stuff, steal things from him, and would verbal abuse him anytime they saw him. They wouldn't stop. The teachers and the principal didn't do anything to stop it. He felt like he didn't have anywhere else to turn to.
Finally, he brought a gun to school to try to scare the guys who kept messing with him and ended up shooting someone else instead. I'm not going to let your brother make anyone else feel like that. And you shouldn't either, because some of the people here are way more dangerous than a low self-esteem kid with a gun.
