<passage>:
The very young man was annoyed. "I don't think I want to go," he blurted. "I don't think I would care to spend two years there." The older man blew a smoke ring and watched it drift toward the air exhaust vent. "You mean you would miss it here, the people you've known and grown up with, the little familiar things that have made up your life here. You're afraid the glamor would wear off and you would get to hate it on The older man smiled. "Still the reluctant heroes," he said, somewhat to himself. Three years on the Moon and they thought he'd be glad to stay for more. Just raise his salary or give him a bonus, the every-man-has-his-price idea. They probably thought he liked it there. you couldn't take a shower, couldn't brush your teeth, and your kidneys didn't work right. And for double his salary they thought he'd be glad to stay for another year and a half. Or maybe three. He should probably be glad he had the to himself. Julius Klein, with that look of ineffable happiness on his face, looked as if he had just squirmed under the tent to his personal covers not mussed, sleeping very lightly. Lord, Chapman thought, I'll be happy when I can see some other faces. "What'd they want?" Klein had one eyelid open and a questioning look on his face. "They wanted me to stay until the next relief ship lands," Chapman whispered back. "What did you say?" looking bitter. "Some of us still have to stay here, you know. Some of us aren't going back today." Klein jerked his thumb toward Dahl's bunk, held a finger to his lips, The others started lacing up their bunks, getting ready for their last day of work on the Moon. In a few hours they'd be relieved by members of the Third research group and they'd be on their way back to Earth. And that includes me, Chapman thought. I'm going home. I'm finally going home. He walked silently to the one small, quartz window in the room. It was Klein came back with the coffee. Chapman took a cup, gagged, and forced were still hanging on the bulkhead. Klein lowered his coffee cup and Klein nodded in agreement. "I haven't been here three years like you Everybody laughed and Chapman turned to Klein. "How about you, Julius?" Klein looked solemn. "Like Dick, I'll first get rid of my obligations to the expedition. Then I think I'll go home and see my wife." They were quiet. "I thought all members of the groups were supposed to be single," Donley said. They ran through it twice. They were beginning to feel it now, Chapman thought. They were going to go home in a little while and the idea was just starting to sink in. "Like they say in the army," Bening said, "you never had it so good. You found a home here." The others chimed in and Chapman grinned. Yesterday or a week ago they couldn't have done it. He had been there too long and he had hated it too much. The party quieted down after a while and Dowden and Bening finished Klein didn't look up. "There wasn't much sense in talking about it. You just get to thinking and wanting—and there's nothing you can do about it. You talk about it and it just makes it worse." "She let you go without any fuss, huh?" "No, she didn't make any fuss. But I don't think she liked to see me go, either." He laughed a little. "At least I hope she didn't." They were silent for a while. "What do you miss most, Chap?" Klein asked. "Oh, I know what we said a little while ago, but I mean He stopped, feeling embarrassed. Klein's expression was encouraging. perfume and the popcorn and the people sweating in the dark." He studied his hands. "I think what I miss most is people—all kinds miss my fellow man more than anything." "Got a girl back home?" Klein asked almost casually. "Yes." "Same reason you didn't mention your wife. You get to thinking about Klein flipped the lid on the specimen box. "Going to get married when "Chap." Klein hesitated a moment. "What happened to Dixon?" "Yes. It worked fine, too. We heard everything that went through his mind at the end." Klein's face was blank. "What's your real job here, Chap? Why does Klein said, "You're not a scientist, are you?" "You wouldn't do it again, though, would you?" "No, I wouldn't." Klein held up his hands. "Look, Chap, I didn't mean you should stay. I Klein had gone out in a last search for rock lichens and Chapman the clothing down farther in the canvas. It was foolish because the bag was already packed and had been for a week. He remembered stalling it off for as long as he could and then the quiet satisfaction about a He hadn't actually needed to pack, of course. In less than twenty-four hours he'd be back on Earth where he could drown himself in toothpaste and buy more tee shirts than he could wear in a lifetime. He could to the Moon. so it will shorten stopover right away." He stopped, feeling a little sorry for Dahl. "It won't be too bad. There'll be new men up here and you'll pass a lot of time getting to know them." "Well, you see," Dahl started, "that's why I came back early. I wanted to see you about stopover. It's that—well, I'll put it this way." He seemed to be groping for an easy way to say what he wanted to. "I'm engaged back home. Really nice girl, Chap, you'd like her if you knew her." He fumbled in his pocket and found a photograph and put it on the desk. "That's a picture of Alice, taken at a picnic we were on together." Chapman didn't look. "She—we—expected to be married when I got back. I never told her about stopover, Chap. She thinks I'll be home tomorrow. I kept thinking, hoping, that maybe somehow—" "You wanted to trade places with me, didn't you, Bob? You thought I might stay for stopover again, in your place?" It hurt to look in Dahl's eyes. They were the eyes of a man who was trying desperately to stop what he was about to do, but just couldn't help himself. "Well, yes, more or less. Oh, God, Chap, I know you want to go home! But I couldn't ask any of the others you were the only one who could, would mean eighteen more months, Chap, but they'd be well-paid months!" Chapman felt tired. The good feeling he had about going home was slowly evaporating. He felt sorrier for Dahl than he could ever remember having felt for anybody. Long after going home, Dahl would remember this. It would eat at him like a cancer. he saw the ship first. "Well, whaddya know!" he shouted. "We got company!" He dashed for his suit. Dowden and Bening piled after him and all three started for the lock. jig of welcome. Then the figures linked arms and started back. Chapman noticed one—it was probably Donley—pat the ship affectionately before he started back. of walking on it and lying on its cool thickness during those sultry summer nights when it was too hot to sleep indoors. Williams blushed. "I thought we could spare a little water for it and maybe use the ultraviolet lamp on it some of the time. Couldn't help but bring it along embarrassed. Chapman sympathized. If he had had any sense, he'd have tried to "I've always wanted to meet the man who's spent more time here than anybody else," he began. "I'm sure you wanted to see me for more reasons than just curiosity." imagine any man would like being here all the time. They're prepared to double your salary—maybe even a bonus in addition—and let you have
