Fair enough. However, you make it sound like I'm completely in the wrong. For all you know, he did get into a physical altercation with this kid, in which case he needs to keep his distance. We're all more interconnected than we'd like to believe and broken kids like that are feeding off of everyone's negative energy. Do they deserve it? Maybe. However, we're not in the stone age to weed such people out. As uncomfortable as it sounds, some fake positive interactions can potentially help to tame this kid, but it's unlikely to happen. My response isn't just aimed at the OP, I'm talking about all kids in general. Doubt think you can change someone into a positive human being through aggression. That responsibility rests with all of us.
