【正文】 You sound to me as though you don39。 39。 said Billy Pilgrim. 39。 clothes were meanwhile passing through poison gas. Body lice and bacteria and fleas were dying by the billions. So it goes. And Billy zoomed back in time to his infancy. He was a baby who had just been bathed by his mother. Now his mother wrapped him in a towel, carried him into a rosy room that was filled with sunshine. She unwrapped him, laid him on the tickling towel, powdered him between his legs, joked with him, patted his little jelly belly. Her palm on his little jelly belly made potching sounds. Billy gurgled and cooed. And then Billy was a middleaged optometrist again, playing hacker39。s. The worst body belonged to a car thief from Cicero, Illinois. Ms name was Paul Lazzar o. He was tiny, and not only were his bones and teeth rotten, but his skin was disgusting. Lazzaro was polkadotted all over with dimesized scars. He had had many plagues of boils. Lazzaro, too, had been on Roland Weary39。s head while he died. So it goes. Derby was forty four years old. He was so old he had a son who was a marine in the Pacific theater of war. Derby had pulled political w ires to get into the army at his age. The subject he had taught in Indianapolis was Contemporary Problems in Western Civilization.

The man was all alone in the nighta ragbag with a round, flat face that glowed like a radium dial. Billy passed w ithin a yard of him. There was barbed wire between them. The Russian did not wave or speak, but he looked directly into Billy39。t hay after all. They were overcoats taken from prisoners who were dead. So it goes. It was the guards39。s car owlishly, cooed calmingly. They had never dealt w ith Americans before, but they surely understood this general sort of freight. They knew that it was essentially a liquid which could be induced to flow slowly toward cooing and light. It was nighttime. The only light outside came from a single bulb which hung from a polehigh and far away. All was quiet outside, except for the guards, who cooed like doves. And the liquid began to flow. Gobs of it built up in the doorway, plopped to the ground. Billy was the nexttolast human being to reach the door. The hobo was the last. The hobo could not flow, could not plop. He wasn39。s room. Her drawers were dumped. her closet was empty. Heaped in the middle of the room were all the possessions she could not take on a honeymoon. She had a Princess telephone extension all her ownon her windowsill Its tiny night light stared at Billy. And then it rang. Billy answered. There was a drunk on the other end.
