"Everything we touch has its own specific shape, texture and firmness, its own special resistance to the pressure we place on it. Every hug feels different because everyone you hug takes up space in the world in a different way. No one else has quite the same contours, the same pleats and ripples in their clothes, the same warmth and weight, the same precise arrangement of flesh and bones. Your own body is a one-off, too. It folds into and nests with someone else’s in a way that no other body can."
