If I was this kid’s parent, I would be majorly upset with you, dork. There are kids you struggle with and you hope will come around. You don’t isolate them and make them feel worse and encourage your class to pull a lord of the flies on them. What kind of a person are you anyway? Have you ever been to church? How do you think Christ would have approached this situation? Are you totally compassionless? I am betting this kid’s parents are in a continuation of their living hell right now along with everyone else who lost people in Tucson. What is wrong with you?
This boy did not belong in college. He was incapable of handling any social interactions. His parents were looking to get him out of the house because they could not deal with him any more and they "didn't have the heart" to institutionalize him -- they wanted him "cared for in the community."
At some point, you have to weigh compassion with the real possibility that someone can't be helped in the environment they are in.
