For a long time he had been white smoke. He did not realize that until he left the hospital, because white smoke had no consciousness of itself. It faded into the white world of their bed sheets and walls; it was sucked away by the words of doctors who tried to talk to the invisible scattered smoke... They saw his outline but they did not realize it was hollow inside.
