Let him leave Jupiter and the first! Mickey Cameron, sitting next to me, dug an elbow into my ribs. "I don't see 'em, Ben," he whispered. "Where do you suppose they are?" I blinked. "Who?" That was something I didn't have to worry about. My parents had died in a strato-jet crash when I was four, so I hadn't needed many of those "You are cordially invited" cards. Just one, which I'd sent to Charlie Taggart. to reach the Moon!" Charlie gulped helplessly, and Mickey said: "Still going to spend the weekend with us, aren't you, Ben?" I shook my head. "Charlie has only twenty-four hours liberty. We're planning to see the town tonight." "Why don't you both come with us?" you asked. "Our folks have their own plane, so it would be no problem. And we've got a big guest room. Charlie, wouldn't you like a home-cooked meal before going back to the Moon?" Charlie's answer was obscured by a sudden burst of coughing. I knew that he'd infinitely prefer to spend his liberty sampling Martian fizzes and Plutonian zombies. But this night seemed too sacred for Charlie's kind of celebration. a tall, willowy man, spectacled, looking the way an academy professor should look. "Ben," he called, "don't forget that offer. Remember you've got two months to decide." "No, thanks," I answered. "Better not count on me." A moment later Mickey said, frowning, "What was he talking about, Ben? Did he make you an offer?" want, isn't it? That's what Mickey used to want." "What did she mean, Mickey?" Mickey looked down at his feet. "I didn't want to tell you yet, Ben. We've been together a long time, planning to be on a rocket. But—" "Yes?" of White Sands Port." He raised his hand to stop me. "I know. It's not so exciting. I'll just live a lot longer. I'm sorry, Ben." I couldn't answer. It was as if someone had whacked the back of my knees with the blast of a jet. "It doesn't change anything, Ben—right now, I mean. We can still have a good weekend." Charlie was muttering under his breath, smoldering like a bomb about to reach critical mass. I shook my head dazedly at him as we got to the "Sure," I said to Mickey, "we can still have a good weekend." "Charlie is funny, isn't he? He's nice and I'm glad he's here, but he's sort of funny." spaceman then." "But he wasn't always a spaceman. Didn't he ever have a family?" I smiled and shook my head. "If he had, he never mentioned it. Charlie doesn't like to be sentimental, at least not on the outside. As far as I know, his life began when he took off for the Moon with Everson." want to go to them. Mickey and I used to dream about them when we were Charlie—a kind of human meteor streaking through space, eternally alone, never finding a home. Or there's the other path. To stay on this little prison of an Earth fill their lungs with the clean rich air of Earth instead of poisonous dust. "I'm sorry," you said. "I didn't mean to make you sad, Ben." "It's all right," I said, clenching my fists. "You made sense—a lot of sense." The next morning Charlie said good-bye in our room. He rubbed his scarred face nervously as he cleared his throat with a series of thin, tight coughs. I scowled, not understanding. "Why, Charlie? What for?" too, about his stiff movements and glassy stare. It was as if he were drugged. I shook the thought away. If Charlie was sick, he wouldn't talk about going to Mars. The medics wouldn't let him go even as far as Luna. We watched him leave, you and Mickey and I. "When will you be back?" you asked. Charlie's hard face contorted itself into a gargoylish grin. "Maybe a have lived the kind of life a kid should live. Mickey noticed my frown. "What's the matter, Ben? Still sore? I feel like a heel, but I'm just not like you and Charlie, I guess. I—" "No, I understand, Mickey. I'm not sore, really." "Well, how about staying with us till you decide? Might as well enjoy Earth life while you can. Okay?" I felt like running from the house, to forget that it existed. I wanted I'll stay, Mickey. Sure." "Can't a spaceman marry, too?" "Yes, a spaceman can marry, but what would it be like? Don't you see, Ben? You'd be like Charlie. Gone for maybe two months, "Do you think I'd dare have children, Ben? Mickey told me what happened on the Cyclops You've got to decide now , I told myself. You can't stay here. You've got to make a choice. You can take Dean Dawson's job and stay with Laura and have kids and a home and live to see what happens in this world sixty years from now. My heart thudded crazily against my chest. It couldn't be! Not Charlie! The audiogram had lied! I pressed the stud again. "... regret to inform you of death of voice droned on. You ran to it, shut it off. "I'm sorry, Ben, so terribly—" Without answering, I walked into my room. I knew it was true now. I remembered Charlie's coughing, his gaunt features, his drugged gaze. The metallic words had told the truth. I sat for a long time on my bed, crying inside, but staring dry-eyed at This was what remained of Charlie after twenty-five years in space. It was a bitter bargain. A statue instead of a wife, yellowed letters instead of children, a medal instead of a home. And now, Laura, it's nearly midnight. You're in your room, sleeping, and the house is silent. It's hard to tell you, to make you understand, and that is why I am Charlie sensed my indecision, that he left these things so that they could tell me what he could not express in words. could look at me, knowing that I would see the worlds he could never live to see. Charlie didn't leave just a few trinkets behind him. He left himself, Laura, for he showed me that a boy's dream can also be a man's dream. He made his last trip to Luna when he knew he was going to die. Heaven knows how he escaped a checkup. Maybe the captain understood and was kind—but that doesn't matter now. want to die in the clean, cool air of Earth? It was because he wanted to die nearer home. His home, Laura, was the be lonely when men like Charlie roam the spaceways? Charlie wanted me to himself that night after graduation. He wanted us to celebrate as spacemen should, for he knew that this would be his last night on Earth. It might have seemed an ugly kind of celebration to you, but he wanted it with all his heart, and we robbed him of it. Because of these things, Laura, I will be gone in the morning. Explain he'll go with me in memory to whatever part of the Galaxy I may live to reach. And so will you, Laura.
