Si didn't bother to before him, Si Pond would have preferred something a bit more tangible 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. But Space Pilot Seymour Pond didn't have their standards. He'd had plenty of time to think it over. It was better to retire on a limited crediting, on a confoundedly limited crediting, than to take the two or three more trips in hopes of attaining a higher standard. haul to the Jupiter satellites, fearfully checking the symptoms of space cafard, the madness compounded of claustrophobia, monotony, boredom and free fall. Plenty of time. Time to decide that a one room mini-auto-apartment, complete with an autochair and built-in beyond belief compared to the conning tower of a space craft. No. Even as Si listened to their speeches, accepted the watch and the cloddy's patriotism, sentiment and desire for public acclaim have miserably failed."

He said, "Nevertheless, both you and I conform with the present generation in finding it far more pleasant to follow one's way of life in the comfort of one's home than to be confronted with the unpleasantness of facing nature's dangers in more adventurous pastimes." dossier revealed him a possible candidate for space pilot, and it was you yourself who talked him into taking the training ... pointing out the more pragmatic advantages such as complete retirement after but six trips, added shares of Basic so that he could enjoy a more comfortable 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 drafted into the working force reserves, served his time, and is now free from toil for the balance of his life.

And then? Then in port, it would be one short drink with the boys, before taking his accumulated pay and heading home. The one short drink would lead to another. And morning would find him, drunk, rolled, tattooed and possibly sleeping it off in jail. So back to sea he'd have to go." 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 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 fellas. You could do the same in life whether you really studied or 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. was burning a hole in his pocket, as the expression went. However, he wasn't going to rush into things. This had to be done correctly. Too many a spree was played by ear. You started off with a few drinks, fell in with some second rate mopsy and usually wound up in a third rate groggery where you spent just as much as though you'd been in the classiest joint in town. Came morning and you had nothing to show for Thus, Si was vaguely aware, it had always been down through the 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. Si was going to do it differently this time. the canopy, dropped the pressurizer and considered the dial. Only one "Nothing too good for ex-Space Pilot Si Pond," he said aloud. sub-shots. Finally, the dash threw a green light and Si opened the Si took his time. Not that he really needed it. It was by far the most the guest might desire and Si touched the control that dilated it to 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 Si cleared his throat. "Hey," he said, "how about letting this one be Si, disconcerted by the sudden reversal, said, "Yeah ... sure." "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. him in the Space Exploration department, he was hot for it." Si was expansive. "Why, sure. In the Space Department we don't have "Well," Si said modestly, "two of my runs were only to the Moon." "... and he said all those things about man's conquest of space. And Si grunted. "Yeah. That's all part of the Doc's scheme to get me to take on another three runs. They're afraid the whole department'll be pressure me into more trips.

You don't meet many people who are interested in space any more. In fact, most people are almost contemptuous, like.
