And if she hadn39。s shoulder and looked at him cheekily. You may be a pain in the neck sometimes, but I39。re ing with me. As Southampton slid astern, Sea Shepherd nosed into the thumping waters of the English Channel. At that moment the sun squinted through a crack in the cloud. On the horizon the sky39。t there. Susan relaxed, smiling at herself. The smile faded fast. She39。s like a fashion store, Susan muttered, shoving the hangers aside to make space for her own clothes. In the bathroom she opened the mirrorfronted cabi on the wall. It was crammed with bottles and jars. Perfume, shampoo, creams ... Susan slammed the cabi shut and pulled a face in the glass. Meanwhile Gary was trying to make friends with Norman. Hard work. Norman proved to be a very serious young man, much given to using long words. Must39。t in the movie. Billy was extrapolating. Everybody turned into a baby, and all humanity, without exception, conspired biologically to produce two perfect people named Adam and Eve, he supposed. Billy saw the war movies backwards then forwardsand then it was time to go out into his backyard to meet the flying saucer. Out he went, his blue and ivory feet crushing the wet salad of the lawn. He stopped, took a swig, of the dead champagne. It was like 7Up. He would not raise his eyes to the sky, though he knew there was a flying saucer from Tralfamadore up there. He would see it soon enough, inside and out, and he would see, too, where it came from soon enoughsoon enough. Overhead he heard the cry of what might have been a melodious owl, but it wasn39。s will was paralyzed by a zap gun aimed at him from one of the portholes. It became imperative that he take hold of the bottom rung of the sinuous ladder, which he did. The rung was electrified, so that Billy39。s brain start working again. There were two peepholes inside the airlockwith yellow eyes pressed to them. There was a speaker on the wall. The Tralfamadorians had no voice boxes. They municated telepathicary. They were able to talk to Billy by means of a puter and a sort of electric an which made every Earthling speech sound. 39。 said the loudspeaker. 39。 Billy licked his lips, thought a while, inquired at last: 39。 That is a very Earthling question to ask, Mr. Pilgrim. Why you? Why us for that matter? Why anything? Because this moment simply is. Have you ever seen bugs trapped in amber?39。Yes.39。Well, here we are, Mr. Pilgrim, trapped in the amber of this moment. There is no why.39。s atmosphere now, put him to sleep. They carded him to a cabin where he was strapped to a yellow BarcaLounger which they had stolen from a Sears amp。s artificial habitat in a zoo on Tralfamadore. The terrific acceleration of the saucer as it left Earth twisted Billy39。t on the flying saucer. He was in a boxcar crossing Germany again. Some people were rising from the floor of the car, and others were lying down. Billy planned to He down, too. It would be lov ely to sleep. It was black in the car, and black outside the car, which seemed to be about two miles an hour. The car never seemed to go any faster than that. It was a long time between clicks, between joints in the track. There would be a click, and then a year would go by, and then there would be another click The train often stopped to let really important trains bawl and hurtle by. Another thing it did was stop on sidings near pris ons, leaving a few cars there. It was creeping across all of Germany, growing shorter all the time. And Billy let himself down oh so gradually now, hanging onto the diagonal crossbrace in the er in order to make himself seem nearly weightless to those he was joining on the floor. He knew it was important that he made himself nearly ghostlike when lying down. He had fotten why, but a reminder soon came. 39。 said a person he was about to nestle with, 39。 Billy didn39。God damn it39。That is you, isn39。 He sat up and explored Billy rudely with his hands. 39。s you, all right. Get the hell out of here.39。Get out of here! I want to sleep!39。Shut up,39。I39。 So Billy stood up again, clung to the crossbrace. 39。 he asked quietly. 39。 39。 said somebody else. 39。 39。 You39。 39。 39。 And now there was an acrimonious madrigal, with parts sung in all quarters of the car. Nearly everybody seemingly, had an atrocity story of something Billy Pilgrim had done to him in his sleep. Everybody told Billy Pilgrim to keep the hell away. So Billy Pilgrim had to sleep standing up, or not sleep at all. And food had stopped ing in through the ventilators, and the days and nights were colder all the time. On the eighth day, the fortyyearold hobo said to Billy, 39。t bad. I can be fortable anywhere.39。You can?39。You think this is bad? This ain39。 There was something about death and the ninth day. There was a death on the ninth day in the car ahead of Billy39。s eye, and all the furniture had claw legs and much carving, which was never dusted to suit. Then Polly had to be fed, the lap dog bed, and a dozen trips upstairs and down to get things or deliver orders, for the old lady was very lame and seldom left her big chair. After these tiresome labors, she must do her lessons, which was a daily trial of every virtue she possessed. Then she was allowed one hou r for exercise or play, and didn3
