'Coward'? [That seems to snap him out of his self-pity, at least a little bit.] You're calling me a coward? Newsflash, smart guy: I can't care about anyone. I'm never going to just turn back into a smiling placid good boy who never does anything wrong. Even if I go and talk to him, it doesn't change anything. Not a thing!

[What's the point of an apology from someone who can't feel remorse? Someone who will just do it again and again?]

... So long as I'm around people, I'm going to hurt them, again and again. That's what I do. Cutting myself off from everyone isn't cowardly, it's logical. I'm removing the problem before it gets worse.
