" BEFORE THE BODY, there is the face, and before the face there is the thin black line between Hector’s nose and upper lip. A twitching filament of anxieties, a metaphysical jump rope, a dancing thread of discombobulation, the mustache is a seismograph of Hector’s inner states, and not only does it make you laugh, it tells you what Hector is thinking, actually allows you into the machinery of his thoughts. "

― Paul Auster , The Book of Illusions
