"No one," John answered, astonished. "Is somebody supposed to?" He was startled at the idea. "Oh, you are concerned about sex. You are also new here. Sex is no problem here, as you will learn." "No problem? Don't you engage in it?" "We have other, and more important things, to do," John answered. His words were lofty but his tone was kind. Zen heard the words but he filed mental reservations about accepting their meaning. Silently he wondered if these kids had all their marbles. Apparently they had not even learned about the birds and the bees. "Anything else I can tell you?" John asked. "You've already told me too much," Zen answered. "I'm afraid to ask you any more questions." The toilet had no flush plumbing. _After use, press the button_, a sign above it said. Zen did just that. No sound of running water followed but the colonel had the dim impression that intensely bright light had flared for a moment. He did not have the courage to look and see what had happened. In some ways, this toilet which disposed of its contents in a flash of light was more significant and possibly more productive of concern than Cuso's blooper or Cuso's lieutenant had been. If the new people found it convenient to disintegrate their sewage, rather than dispose of it by the conventional method, what else could they do? Zen shook his head to indicate to himself how amazed he was. John thought he wanted more information and started to ask a question, which the colonel hastily interrupted. "Don't tell me any more. There are limits to what my liver and lights will stand." "What have your liver and lights to do with this?" "Nothing at all. That was only a figure of speech." As they returned through the gallery, he saw that the bronze girl was still going through her rhythmic dance in time to the slow music. The sight of that perfectly formed nude body slowly swaying in the small room sent such a surge of excitement through Kurt Zen that he hastily turned his eyes away. If he was going to live in this place very long, they would have to make some new rules. How could any human being stay in bed alone when that beautiful bronze creature was going through her swaying dance? "What is she doing, learning to be a strip-tease dancer?" he asked. "Perfect muscular control. This is one of the exercises we all learn," John answered. "What's a strip-tease dancer?" "Nothing you ever heard of," Zen answered. "But while she is developing her muscular control, what is she doing to the endocrinal system of every male in the place?" "Not a thing," John said, astonished again. Zen had grave doubts that the tall youth knew what he was talking about.
