【正文】 dorians on the night of his daughter39。s wedding. He hadn39。t been missed, he said, because the Tralfamadorians had taken him through a time warp, so that he could be on Tralfamadore for years, and still be away from Earth for only a microsecond. Another month went by without incident, and then Billy wrote a letter to the Ilium News Leader, which the paper published. It described the creatures from Tralfamadore. The letter said that they were two feet high, and green., and shaped like plumber39。s friends. Their suction cups were on the ground, and their shafts, which were extremely flexible, usually pointed to the sky. At the top of each shaft was a little hand with a green eye in its palm. The creatures were friendly, and they could see in four dimensions. They pitied Earthlings for being able to see only three. They had many wonderful things to teach Earthlings, especially about time. Billy promised to tell what some of those wonderful things were in his next letter. Billy was working on his second letter when the first letter was published. The second letter started out like this: 39。The most important thing I learned on Tralfamadore was that when a person dies he only appears to die. He is still very much alive in the past, so it is very silly for people to cry at his funeral. All moments, past, present and future, always have existed, always will exist. The Tralfamadorians can look at all the different moments just that way we can look at a stretch of the Rocky Mountains, for instance. They can see how permanent all the moments are, and they can look at any moment that interests them. It is just an illusion we have here on Earth that one moment follows another one, like beads on a string, and that once a moment is gone it is gone forever. 39。When a Tralfamadorian sees a corpse, all he thinks is that the dead person is in a bad condition in that particular moment, but that the same person is just fine in plenty of other moments. Now, when I myself hear that somebody is dead, I simply shrug and say what the Tralfamadorians say about dead people, which is so it goes.39。 And so on. Billy was working on this letter in the basement rumpus room of his empty house. It was his housekeeper39。s day off. There was an old typewriter in the rumpus room. It was a beast. It weighed as much as a storage battery. Billy couldn39。t carry it very far very easily, which was why he was writing in the rumpus room instead of somewhere else. The oil burner had quit. A mouse had eaten through the insulation of a wire leading to the thermostat. The temperature in the house was down to fifty degrees, but Billy hadn39。t noticed. He wasn39。t warmly dressed, either. He was barefoot, and still in his pajamas and a bathrobe, though it was late afternoon. His bare feet were blue and ivory. The cockles of Billy39。s heart, at any rate, were glowing coals. What made them so hot was Billy39。s belief that he was going to fort so many people with the truth about time. His door chimes upstairs had been ringing and ringing. It was his daughter Barbara up there wanting in. Now she let herself in with a key, crossed the floor over his head calling, 39。Father? Daddy, where are you?39。 And so on. Billy didn39。t answer her, so she was nearly hysterical, expecting to find his corpse. And then she looked into the very last p lace there was to lookwhich was the rumpus room. 39。Why didn39。t you answer me when I called?39。 Barbara wanted to know, standing there in the door of the rumpus room. She had the afternoon paper with her, the one in which Billy described his friends from Tralfamadore. 39。I didn39。t hear you,39。 said Billy. The orchestration of the moment was this: Barbara was only twentyone years old, but she thought her father was senile, even though he was only fortysixsenile because of damage to his brain in the airplane crash. She also thought that she was head of the family, since she had had to manage her mother39。s funeral, since she had to get a housekeeper for Billy, and all that. Also, Barbara and her husband were having to look after Billy39。s business interests, which were considerable, since Billy didn39。t seem to give a damn for business any more. All this responsibility at such an early age made her a bitchy flibbertigibbet. And Billy, meanwhile, was trying to hang onto his dignity, to persuade Barbara and everybody else that he was far from senile, that, on the contrary, he was devoting himself to a calling much higher than mere business. 44 He was doing nothing less now, he thought, then prescribing corrective lenses for Earthling souls. So many of those souls were lost and wretched, Billy believed, because they could not see as well as Ws little green friends on Tralfamadore. 39。Don39。t lie to me, Father,39。 said Barbara. 39。I know perfectly well you heard me when I called.39。 This was a fairly pretty girl, except that she had legs like an Edwardian grand piano. Now she raised hell with him about the letter in the paper. She said he was making a laughing stock of himself and everybody associated with him. 39。Father, Father, Father,39。 said Barbara, 39。what are we going to do with you? Are you going to force us to put you where your mother is?39。 Billy39。s mother was still alive. She was in bed in an old people39。s home called Pine Knoll on the edge of Ilium. 39。What is it about my letter that makes you so mad?39。 Billy wanted to know. 39。It39。s all just crazy. None of it39。s true! 39。 39。It39。s all true. 39。 Bill39。s anger was not going to rise with hers. He never got mad at anything. He was wonderful that way. 39。There is no such pla as Tralfamadore.39。 39。It can39。t be detected from Earth, if that39。s what you mean,39。 said Billy. 39。Earth can39。t be detected from Tralfamadore, as far as that goes. They39。re both very small. They39
