"The thing about Simon Limbres’s heart, this human heart, is that, since the moment of his birth, when its rhythm accelerated, as did the other hearts around it, in celebration of the event, the thing is, that this heart, which made him jump, vomit, grow, dance lightly like a feather or weigh heavy as a stone, which made him dizzy with exhilaration and made him melt with love, which filtered, recorded, archived—the black box of a twenty-year-old body—the thing is that nobody really knows it."
