What society and the news media will judge you by if you go postal and machinegun your schoolmates. They'll read your sad little poems on the evening news, reprint your abstract doodles in the newspaper. They'll make you Different, Strange, possibly a nazi (you drew a quick sketch of yourself being trampled by a regiment of goose stepping soldiers). Everyone will know you were a freak, a sad little teenager, with bad parents, because that's what they want to hear. They'll go home, and sleep well, smug in the knowledge that it could never happen to them.
