I spoke with some of [Amy's brother] Seth’s friends, now men in their forties, and more than one started crying at the mention of his name. They attested to his mischievous vitality and his self-possession. Once, in middle school, he was surrounded in the cafeteria by classmates who taunted him for carrying his violin and suggested, mockingly, that he play it. Seth removed the instrument from its case, raised his bow, and began to play, beautifully, until the bullies were cowed into silence. “He called their bluff,” [Seth's best friend] Agnew, who observed the episode, remembered.
