remember his name. He only wondered vaguely why the cloddy had turned up at all. In common with recipients of gold watches of a score of generations The fact of the matter was, Si knew that his retiring had set them back. They hadn't figured he had enough shares of Basic to see him through decently. Well, possibly he didn't, given their standards. find contentment for a mighty long time. Possibly somebody like Doc Girard-Perregaux might be horrified at the idea of living in a No. Even as Si listened to their speeches, accepted the watch and Girard-Perregaux, was concerned. Doctor Girard-Perregaux was convinced Gubelin would have even worn facial hair, had he but a touch more courage. Gubelin longed for yesteryear, a seldom found phenomenon under than is to be found there. He is an average young man. Born in our Ultrawelfare State, he was guaranteed his fundamental womb-to-tomb security by being issued that minimum number of Basic shares in our society that allows him an income sufficient to secure the food, clothing, shelter, medical care and education to sustain a low level of subsistence. Percentages were against his ever being drafted into industry. Automation being what it is, only a fraction of the population is ever called up. But Pond was. His industrial aptitude dossier revealed him a possible candidate for space pilot, and it was life than most and the fame that would accrue to him as one of the very few who still participate in travel to the planets. Very well. He was sold. Took his training, which, of course, required long years of drudgery to him. Then, performing his duties quite competently, he made his six trips. He is now legally eligible for retirement. He was drafted into the working force reserves, served his time, and is now free from toil for the balance of his life. Why should he listen to our pleas for a few more trips?" He said, "No, he hasn't. Few there are who have, nowadays. Man has always paid lip service to adventure, hardships and excitement, but in actuality his instincts, like those of any other animal, lead him to the least dangerous path. Today we've reached the point where no one need face danger—ever. There are few who don't take advantage of the Looking over the rim of his glass, his eyes narrowed in thought as his Gubelin blinked at him. excuse would do. Back when he had finished basic education at the age of twenty-five and was registered for the labor draft, there hadn't been a chance in a hundred that he'd have the bad luck to have his name pulled. But when it had been, Si had celebrated. When he had been informed that his physical and mental qualifications were such that he was eligible for the most dangerous occupation in Now it was all over. At the age of thirty he was retired. Law prevented him from ever being called up for contributing to the country's labor needs again. And he most certainly wasn't going to volunteer. He had taken his schooling much as had his contemporaries. There wasn't any particular reason for trying to excell. You didn't want to get the reputation for being a wise guy, or a cloddy either. Just one of the not. You had your Inalienable Basic stock, didn't you? What else did you need? It had come as a surprise when he'd been drafted for the labor force. In the early days of the Ultrawelfare State, they had made a mistake in adapting to the automation of the second industrial revolution. They had attempted to give everyone work by reducing the number of working hours in the day, and the number of working days in the week. It finally became ludicrous when employees of industry were working but two days a week, two hours a day. In fact, it got chaotic. It became obvious that it was more practical to have one worker putting in thirty-five hours a week and getting to know his job well, than it was to have a score of employees, each working a few hours a week and none of them ever really becoming efficient. The only fair thing was to let the technologically unemployed remain unemployed, with their Inalienable Basic stock as the equivalent of unemployment insurance, while the few workers still needed put in a reasonable number of hours a day, a reasonable number of weeks a year and a reasonable number of years in a life time. When new employees were needed, a draft lottery was held. All persons registered in the labor force participated. If you quite so little for his money as that loneliest of all workers, he who must leave his home for distant lands, returning only periodically and usually with the salary of lengthy, weary periods of time to be spent hurriedly in an attempt to achieve the pleasure and happiness so long denied him. works. But nothing but the best. To start off, he dressed with great care in the honorable performed anything of value to society. The efforts of most weren't needed. Those few who did contribute were awarded honors, decorations, titles. Attired satisfactorily, Si double-checked to see that his credit He didn't take the time to flick on the menu, next to the auto-dining table, nor to check the endless potables on the autobar list. All that, he well knew, would be superlative. Besides, he didn't plan to dine or do much drinking in his suite. He made a mock leer. Not unless he around in second-class groggeries, no eating in automated luncheterias. This time, be it the only time in his life, he was going to frolic in moment and looked about. He'd never been in a place like this, either. However, he stifled his first instinct to wonder about what this was going to do to his current credit balance with an inner grin and made There was actually a bartender. Si Pond suppressed his astonishment and said, offhand, attempting an The drinks in the Kudos Room might be concocted by hand, but Si noticed He put his credit card on the screen immediately before him when the drink came, and had to quell his desire to dial for a balance check, so to his highest expectations, and then swiveled slightly on his stool to take a look at the others present. To his disappointment, there were no recognizable celebrities. None He turned back to his drink and noticed, for the first time, the girl who occupied the stool two down from him. Si Pond blinked. He blinked She looked at him coldly, turned to the bartender and murmured, "A Far Si cleared his throat. "Hey," he said, "how about letting this one be The bartender said hurriedly, "I beg your pardon, sir...." Si, disconcerted by the sudden reversal, said, "Yeah ... sure." She was obviously both taken back and impressed. "Why," she said, Si, carrying his glass, moved over to the stool next to her. "Call me Si," he said. "Everybody calls me Si." "Si," Si said, gratified. Holy Zoroaster, he'd never seen anything current sex symbols, but never in person. "Call me Si," he said again. "I been called Si so long, I don't even know who somebody's talking to such that it was obvious she hadn't quite adjusted as yet to having met him. much time for formality. Everybody's just Si, and Doc, and Jim. Like She looked down into the drink the bartender had placed before her, as though avoiding his face. "I ...
