Because beyond their practical function, all gestures have a meaning that exceeds the intention of those who make them; when people in bathing suits fling themselves into the water, it is joy itself that shows in the gesture, notwithstanding any sadness the divers may actually feel. When someone jumps into the water fully clothed, it is another thing entirely: the only person who jumps into the water fully clothed is a person trying to drown; and a person trying to drown does not dive headfirst; he lets himself fall: thus speaks the immemorial language of gestures.
