"When practicing his pool game, Crackhead Rob would line up all the balls down the centre of the table and mechanically shoot each one into the same pocket, as if it was just that simple. He missed none of them. He selected a pocket, and then the balls all went there, one at a time. Watching him, I began to notice how he introduced various types of spin to the cue ball, how his attention was as much about controlling the destination of the cue ball as it was aiming for a pocket. Between practice sessions, he’d drink beer and worked on the NYT crossword on the bar. This is how I first noticed that he was secretly, sort of, a genius. He finished the crossword every time, nailed it with the same unnerving accuracy of his bank shot."
