From No Psychos, No Druggies, No Stooges:
Michael’s problems started, according to his mother, around age 3, shortly after his brother Allan was born. At the time, she said, Michael was mostly just acting “like a brat,” but his behavior soon escalated to throwing tantrums during which he would scream and shriek inconsolably. These weren’t ordinary toddler’s fits. “It wasn’t, ‘I’m tired’ or ‘I’m frustrated’ — the normal things kids do,” Anne remembered. “His behavior was really out there. And it would happen for hours and hours each day, no matter what we did.” For several years, Michael screamed every time his parents told him to put on his shoes or perform other ordinary tasks, like retrieving one of his toys from the living room. “Going somewhere, staying somewhere — anything would set him off,” Miguel said. These furies lasted well beyond toddlerhood. At 8, Michael would still fly into a rage when Anne or Miguel tried to get him ready for school, punching the wall and kicking holes in the door. Left unwatched, he would cut up his trousers with scissors or methodically pull his hair out. He would also vent his anger by slamming the toilet seat down again and again until it broke.
When Anne and Miguel first took Michael to see a therapist, he was given a diagnosis of “firstborn syndrome”: acting out because he resented his new sibling. While both parents acknowledged that Michael was deeply hostile to the new baby, sibling rivalry didn’t seem sufficient to explain his consistently extreme behavior.
By the time he turned 5, Michael had developed an uncanny ability to switch from full-blown anger to moments of pure rationality or calculated charm — a facility that Anne describes as deeply unsettling. “You never know when you’re going to see a proper emotion,” she said. She recalled one argument, over a homework assignment, when Michael shrieked and wept as she tried to reason with him. “I said: ‘Michael, remember the brainstorming we did yesterday? All you have to do is take your thoughts from that and turn them into sentences, and you’re done!’ He’s still screaming bloody murder, so I say, ‘Michael, I thought we brainstormed so we could avoid all this drama today.’ He stopped dead, in the middle of the screaming, turned to me and said in this flat, adult voice, ‘Well, you didn’t think that through very clearly then, did you?’ ”
