It seems to me that his melodramatic over-reaction to Martha's being forced to reveal a secret when he'd have not had that happen is the perfect jumping off point. Our boy simply did not want to listen to any 'excuse' she might make about how her posse didn't care a fart in a high wind about his feelings. He was sure that the only reason that she pretended to like him in the first place was so that she could humiliate him and laugh at him for daring to think that he too could have what other people have.
Time and again, the old hobgoblin about how people were only using him so that they could kick him in the face and tell him that no one was ever going to like him and he should just accept being shoved off into a corner and end up only being remembered when people want to laugh a malicious laugh at that kid EVERYONE hates for no reason would arise to screw up his life. The problem is that on some level, Michael has to believe this sort of rubbish rather than face harsh truths that 'cannot' be true:
- "I am a very pessimistic person who always expects the worst in any situation."
- "I find it very difficult to trust the people around me."
- "I despise having to do things that don't interest me."
- "I take a sick delight in the misery of people who get in my way."
- "I would rather not accept responsibility for my mistakes and bad behaviour."
- "I find it difficult to sympathize with other people because since their pain is not my own, it can't really be said to matter."
- "I am not really especially curious as to why people do what they do."
- "I hate the idea that people can do what they want without running it by me first."
- "I am filled with the desire to tyrannize and humiliate that I ascribe to others."
- "I am primarily motivated by envy."
- "I hate the idea that other people can get attention when it's all supposed to be for me."
- "Deep down, I really do think that I'm the only person who matters and people only exist to do what I want."
