After a while even he ceased to find it surprising that he spent most of his time alone. By his late 20s he thought of himself as the sort of person who didn’t have friends. He’d gone through Santa Teresa High School, in San Jose, U.C.L.A., and Vanderbilt University School of Medicine, and created not a single lasting bond. What friendships he did have were formed and nurtured in writing, by email; the two people he considered to be true friends he had known for a combined 20 years but had met in person a grand total of eight times. “My nature is not to have friends,” he said. “I’m happy in my own head.” Somehow he’d married twice. His first wife was a woman of Korean descent who wound up living in a different city (“She often complained that I appeared to like the idea of a relationship more than living the actual relationship”) and his second, to whom he was still married, was a Vietnamese-American woman he’d met on Match.com. In his Match.com profile, he described himself frankly as “a medical resident with only one eye, an awkward social manner, and $145,000 in student loans.” His obsession with personal honesty was a cousin to his obsession with fairness.
Obsessiveness—that was another trait he came to think of as peculiar to himself. His mind had no temperate zone: he was either possessed by a subject or not interested in it at all. There was an obvious downside to this quality—he had more trouble than most faking interest in other people’s concerns and hobbies, for instance—but an upside, too. Even as a small child he had a fantastic ability to focus and learn, with or without teachers. When it synched with his interests, school came easy for him—so easy that, as an undergraduate at U.C.L.A., he could flip back and forth between English and economics and pick up enough pre-medical training on the side to get himself admitted to the best medical schools in the country. He attributed his unusual powers of concentration to his lack of interest in human interaction, and his lack of interest in human interaction … well, he was able to argue that basically everything that happened was caused, one way or the other, by his fake left eye.
