It took balls to do what he did because if he failed—and he had failed—he’d end up where he was. He hadn’t accomplished the things of which he’d dreamed, and now he couldn’t even get done the very basic things that most adults did—like pay his bills, for example (a most unpleasant form letter—and purple—was lying on his cluttered desk, somewhere, from Commonwealth Gas), or alphabetize his books. And when he tried, when he took the books off the shelves in order to put them back in alphabetical order, he became so discouraged at the impossibility of categorizing them properly that he just left them lying there, heaped upon the floor. He worked out a lot but he didn’t apply moisturizer to his skin at night, and he seldom flossed. And then there was the Google. . . .
