The dancers at the center of the circle finally bowed out with small garlands of flowers on their heads that signified their reaching adulthood. Acrobats then took the stage and went through a dizzying routine, and they in turn were succeeded by a native singer. They were all excellent, Eckert thought. If anything, they were too It was Eckert who had come into his office several days ago and told Eckert had come into his office without saying a word and had watched had come of good stock. There had been no mental instability in his family for as far back as the genetic records went. He had been raised in a middle-class neighborhood and attended a local grammar school where he had achieved average grades and had given his instructors the such honors. But try getting a picture of him by reading the records, resurrect him from a page of black print. Would he be human? Would he be flesh and blood? Hell, no! In the statistics Pendleton was the All-Around Boy, the cold marble statue with the finely chiseled muscles and the smooth, blank sockets where the eyes should be. Maybe someday fate would play a trick on a hero-worshiping public and there would actually be kids like that. But they wouldn't be human they wouldn't be born. Parents would get them by sending in so many box tops. He was drowsy didn't. But sometimes they were murdered. the ceiling told how close they were to takeoff. His head was thick with drowsiness, his eyelids a heavy weight that he knew he couldn't keep open much longer. Eckert and he had been chosen to go to Tunpesh and investigate. The two The thin red line was practically microscopic now and Templin could feel his lashes lying gently on his cheeks. But he wasn't asleep—not Warm breezes rustled through Eckert's graying hair and tugged gently as though it grew fast—it would certainly have plenty of time to grow before the next ship landed. He looked at the slim, dwindling shape that was the rocket, and was suddenly, acutely aware that he and Templin would be stranded for six at that, away from the din and the hustle and confusion, spending the time in a place where the sun was warm and inviting. I must be getting old , he thought, thinking about the warmth and comfort. Like old dogs and octogenarians. Templin was looking at the scenery with a disappointed expression on Eckert nodded agreement. "It wouldn't fit, would it? It would be like a It looked fairly primitive, Eckert thought, and yet it didn't have the earmarks, the characteristics of most primitive villages. It didn't seem cluttered or dirty and you didn't feel like beating a hasty retreat when the wind was blowing toward you. A few adults were watching them curiously and the usual bunch of kids that always congregated around rocketports quickly gathered. Eckert stared at them for a moment, wondering what it was that seemed odd about them, and they stared back with all the alert dignity of childhood. They finally came out on the field and clustered around him and Templin. Templin studied them warily. "Better watch them, Ted. Even kids can be dangerous." It's because you never suspect kids , Eckert thought, you never think But the idea still didn't go with the warm sun and the blue sky and the piny scent of the trees. One of the adults of the village started to walk toward them. "I'd be very careful what I did," Eckert said softly. "I would hate to start something merely because I misunderstood their intentions." The committee of one was a middle-aged man dressed in a simple strip of white cloth twisted about his waist and allowed to hang freely to his knees. When he got closer, Eckert became less sure of his age. He had the firm, tanned musculature of a much younger man, though a slightly seamed face and white hair aged him somewhat. Eckert still had the feeling that if you wanted to know his exact age, you'd have to look at his teeth or know something about his epiphyseal closures. "You are menshars from Earth?" The voice was husky and pleasant and and made a few mental notes. He wasn't bowing and scraping like most natives who weren't too familiar with visitors from the sky, and yet he was hardly either friendly or hostile. been the anthropologist. "We have had visitors from Earth before." He hesitated a moment He was polite, Eckert thought. He didn't ask what they were there Eckert and Templin took a quick tour of the few rooms. They were well furnished, in a rustic sort of way, and what modern conveniences they didn't have they could easily do without. The youngsters who had carried their luggage left it outside and quietly faded away. It was getting dark Eckert opened one of the boxes they had brought along, knew usually appealed to the primitive imagination. Eckert shrugged. "That's one of the things you do out of habit, try "That's not very typical of a primitive society, is it?" "No, I'm afraid it's not." Eckert started unpacking some of the boxes. "You know, Ray, I got a kick out of the kids. They're a healthy-looking lot, aren't they?" "Too healthy," Templin said. "There didn't seem to be any sick ones or ones with runny noses or cuts or black eyes or bruises. It doesn't seem natural." "They're probably just well brought-up kids," Eckert said sharply. "Maybe they've been taught not to get in fights or play around in the mud on the way home from school." He felt faintly irritated, annoyed at the way Templin had put it, as if any deviation from an Earth norm was they're playing a rehearsed part. Here we are, from an entirely different solar system, landed in what must be to them an unusual manner. They couldn't have seen rockets more than three or four times before. It should still be a novelty to them. And yet how much curiosity did they show? Hardly any. Was there any fear? No. And the cute, harmless little kids." He looked at Eckert. "Maybe that's what we're supposed to think—just an idyllic, harmless society. Maybe He was keyed up, jumpy, Eckert realized. He would probably be seeing even realize. He wondered what Templin would do if he ever found out feelings and emotions would almost exactly be duplicated in Templin's. There were disadvantages in taking Templin, too. "Just how primitive do you think the society is, Ted?" "I don't think it's primitive at all. There are too many disparities. Their knowledge of a lot of things is a little more than empirical knowledge Eckert sighed and watched a fat bug waddle across a small patch of seemed likely to turn into a vendettist. It meant that Eckert would Eckert rolled up the thin, slatted blinds and stared out at the "They grow their women nice, don't they?" "Physically perfect, like the men," Templin grumbled. "You could get an inferiority complex just from watching the people here. Everybody's so One of the hardest things to learn in a foreign culture, Eckert and Templin had been invited. It was a good chance to observe native He looked at Templin, sitting across from him in the huge circle, and shrugged mentally. Templin looked as if he was about to break down and in Templin's getting excited and doing something he was bound to regret Eckert had a sudden clammy feeling which quickly passed away. What Nayova had said was something he'd make sure Templin never heard about. information together. They probably had a taboo about self-destruction knelt before Nayova. When he clapped his hands sharply, they retreated to the center of the circle and began the slow motions of a native obscene ."
