<passage>:
by ... Roger Dee Just a one-eyed dog named Charlie and a crippled boy named Joey—but between them they changed the face of the universe ... perhaps. Inearly stumbled over the kid in the dark before I saw him. staring upward with such absorbed intensity that he didn't even know I was there until I spoke. "Anything wrong, Joey?" I asked. He said, "No, Roy," without taking his eyes off the sky. For a minute I had the prickly feeling you get when you are watching a couldn't help wondering why he'd turned to watching the sky instead. "What're you looking for up there, Joey?" I asked. He didn't move and from the tone of his voice I got the impression Joey that time too, but he wasn't moving stars then. He was just saw Doc asleep in his bunk. Doc put the snapper steaks to cook. He told me more about our neighbors while we killed the beer. The Ponds were permanent residents. The kid—his name was Joey and he was ten—was a polio case who hadn't walked for over a year, and his mother was a waitress at a roadside joint named the Sea Shell Diner. Joey was hospitalized with polio." "Tough," I said, thinking of the kid sitting out there all day in his wheelchair, straining his eyes across the palmetto flats. "You mean looking its screwball funniest with our arguments one or the other of us would look out the window and see Joey Pond in his wheelchair, waiting for a one-eyed dog named Charlie to come trotting home across the palmetto flats. He was always there, day or night, until his the kid didn't want another mutt because he had what Doc called a psychological block. "Charlie was more than just a dog to him," Doc said. "He was a sort of point in living." I could see it when Doc put it that way. The dog had spent more time with Joey than Ethel had, and the kid felt as safe with him as he'd have been with a platoon of Marines. And Charlie, being a one-man dog, had depended on Joey for the affection he wouldn't take from anybody else. The dog needed Joey and Joey needed him. Together, they'd been a natural. At first I thought it was funny that Joey never complained or cried when Charlie didn't come home, but Doc explained that it was all a part of this psychological block business. If Joey cried he'd be admitting that Charlie was lost. So he waited and watched, secure in his belief that Charlie would return. The Ponds got used to Doc and me being around, but they never got what you'd call intimate. Joey would laugh at some of the droll things Doc said, but his eyes always went back to the palmetto flats and the highway, looking for Charlie. And he never let anything interfere with Old Cloehessey would lean on his bike and take off his sun helmet and mop his bald scalp, scowling while he pretended to think. Then he'd say, "Not today, Joey," or, "Thought so yesterday, but this I knew what he meant and wished I didn't. Ethel had finally told the kid that Charlie wasn't coming back, not ever. That's why I was worried about Joey when I came home the next evening and found him watching the sky instead of the palmetto flats. It meant he'd given up waiting for Charlie. And the quiet way the kid spoke of moving the stars around worried me more, because it sounded outright crazy. "Books for Joey," Doc said. "Ethel and I agreed this morning that the story. Joey still didn't know that Charlie was dead, but his waiting was over because no dog could be expected to find his way home from Michigan. "We've got to give the boy another interest," Doc said, putting away the books and puncturing another beer can. "Joey has a remarkable talent for concentration—most handicapped children have—that could be the end of him if it isn't diverted into safe channels." I thought the kid had cracked up already and said so. stopped instead of burning out the way a falling star seems to do, partly because anything that excites Doc Shull that much is something to think about. neither of us got to sleep right away. "Maybe we ought to look for another interest in life ourselves instead of drumming up one for Joey," Doc said. He meant it as a joke but it had a shaky sound "Something besides getting beered up every night, Doc laughed at that, sounding more like his old self. "No, Roy. No two people ever had instantaneous and identical hallucinations." "Look," I said. "I know this sounds crazy but maybe Joey—" Doc wasn't amused any more. "Don't be a fool, Roy. If those stars really moved you can be sure of two things—Joey had nothing to do suggested to Doc, only half joking, that maybe the Pup had stayed put because it wasn't bright enough to suit Joey's taste, but Doc called me down sharp. "Don't joke about Joey," he said sternly. "Getting back to to reach us. That means it started moving when Joey was only eighteen months old. The speed of light is a universal constant, Roy, and I pointed out. "I'm not saying that Joey really moved those damn stars, Doc, but if he did he could have moved the light along with But Doc wouldn't argue the point. "I'm going out for air," he said. I trailed along, but we didn't get farther than Joey's wheelchair. There he sat, tense and absorbed, staring up at the night sky. Doc and night before. The pattern they made still didn't look like anything in particular. I left Doc shaking his head at the sky and went over to give Joey, who "You'll know when I'm through," he said. I told Doc about that after we'd bunked in, but he said I should not encourage the kid in his crazy thinking. "Joey's heard everybody talking about those stars moving, the radio newscasters blared about it, so he's excited too. But he's got a lot more imagination than most Doc got up and went back to his own bunk. "Maybe you're right. We'll the gloom I could see a stack of books on the grass beside him, books Doc had given him to study. The thing that stopped me was that Joey mention the stars. But Joey spoke first. "Doc said this morning that I ought not to move any more stars," the "Doc says that if I can do what I've been doing to the stars then it ought to be easy to move my own feet," Joey said. "And he's right, It's a pity things don't happen in life like they do in books, because a first-class story could be made out of Joey Pond's knack for moving things by looking at them. In a book Joey might have saved the world or destroyed it, depending on which line would interest the most ever go away, in case you've wondered about it—it's up there in the sky where you can see it any clear night—but it will never be finished because Joey Pond lost interest in it when he learned to walk again. Walking was a slow business with Joey at first because his legs had time came around he was playing softball and fishing in the Gulf with a gang of other kids on Sundays. School opened up a whole new world to Joey and he fitted himself into the routine as neat as if he'd been doing it all his life. He learned a lot there and he forgot a lot that he'd learned for himself by being
