<passage>:
strange events that scientists and historians, unable to explain logically, have dismissed with such labels as "supernatural," "miracle," etc. But there are those among us whose simple faith I think he actually forgot about those stars along with other things because kids—normal kids—forget their pain quickly. It's a sort of defense mechanism, Doc says, against the disappointments of this life. Joey—but between them they changed the face of the universe "Anything wrong, Joey?" I asked. eye. Doc says that footloose migratories like him and me forget old associations as quick as kids do—and for the same good reason—so I'm not especially interested now in where Ethel and Joey Pond are or how You're puzzled and a little spooked until you realize that the reason you can predict the action so exactly is because you've seen the same "What're you looking for up there, Joey?" I asked. I wish I'd asked Joey or Ethel, before they moved away, how Charlie thing happen somewhere else a long time ago. I forgot the feeling when "I'm moving some stars," he said softly. Joey that time too, but he wasn't moving stars then. He was just bathroom this afternoon while his mother was away at work, and my selflessness had its just reward." Sometimes it's hard to tell when Doc is kidding. He's an educated gamble at that, because Doc has a way with him when he bothers to use it maybe that's why he bums around with me after the commercial Joey was hospitalized with polio." the kid didn't want another mutt because he had what Doc called a psychological block. had depended on Joey for the affection he wouldn't take from anybody 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 his belief that Charlie would return. The Ponds got used to Doc and me being around, but they never got what Then he'd say, "Not today, Joey," or, "Thought so yesterday, but this that changed Joey's routine and a lot more with it. It left a mark That's why I was worried about Joey when I came home the next evening moving the stars around worried me more, because it sounded outright under his arm. Doc was stone sober, which surprised me, and he was hot and tired from a shopping trip to Tampa, which surprised me more. It "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 "Moving stars ?" Doc said when I told him. "Good Lord, Roy—" It moved! " it's called—it moved a good sixty degrees, then stopped dead !" I sat up and took notice then, partly because the star really had 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. 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 with it, and the papers will explain everything tomorrow." authority they could reach, and astronomers were going crazy more about the stars than I'd learned in a lifetime. Doc, as I've said little companion—astronomers called it the "Pup" because Sirius was the Dog Star—hadn't moved, which puzzled the astronomers no end. I 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 "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 astronomers say it can't be changed." 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 them, couldn't he?" in time to see the stars start moving again. stars flashed across the sky and joined the group that had moved the I left Doc shaking his head at the sky and went over to give Joey, who Doc couldn't hear, then I asked him how things were going. "Slow, Roy," he said. "I've got 'most a hundred to go, yet." "Then you're really moving those stars up there?" He gave me a very small smile. "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 people, because he's a cripple, and he could go off on a crazy tangent because he's upset about Charlie. The thing to do is give him a logical explanation instead of letting him think his fantasy is a fact." Doc was taking all this so hard—because it was upsetting things he'd taken for granted as being facts all his life, like those astronomers who were going nuts in droves all over the world. I didn't realize how upset Doc really was, though, till he woke me up at about 4:00 a.m. "I can't sleep for thinking about those stars," he said, sitting on scared ." That from Doc was something I'd never expected to hear. It startled me wide enough awake to sit up in the dark and listen while he unloaded his worries. "I'm afraid," Doc said, "because what is happening up there isn't right or natural. It just can't be, yet it is." It was so quiet when he paused that I could hear the blood swishing in delicately balanced as a fine watch. If that balance is upset too far our world will be affected drastically." Ordinarily I wouldn't have argued with Doc on his own ground, but I could see he was painting a mental picture of the whole universe crashing together like a Fourth of July fireworks display and I was those stars there. So how do they know that whoever put them there won't move them again? I've always heard that if a man had faith enough he could move mountains. Well, if a man has the faith in himself that Joey's got maybe he could move stars, too." Doc sat quiet for a minute. "' There are more things, Horatio.... tonight as ever, Roy. Do you really believe Joey is moving those stars?" Doc had given him to study. The thing that stopped me was that Joey mention the stars. But Joey spoke first. that Doc is an awfully wise man?" I said I'd always thought so, but why? "Doc said this morning that I ought not to move any more stars," the kid said. "He says I ought to concentrate instead on learning how to "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, 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 readers and bring the writer the fattest check, but of course it didn't really turn out either way. It ended in what Doc Shull called an anticlimax, leaving everybody happy enough except a few astronomers who like mysteries anyway or they wouldn't be astronomers in the first
