I was rather hoping for a positive story about isolation. Not everybody who doesn't like going out is sick, afraid, or has taken some kind of a wrong turn.
Unfortunately, especially for this guy, he does seem to have reacted against the world badly rather than making a level decision. It's easy to understand his frustration - we've all been stymied, misunderstood, pressured or heckled simply for being. However I do think there's a difference between storming out of a room and deciding that you'd like to leave. The way he pinpoints small, specific events that made a disproportionate impact on him and compelled him into solitude makes me think he was more of a stormer.
I hope he gets something good out of posting his story online, but I am afraid that he might draw more of the flak he'd initially been keen to avoid.
