like him. But it's a longish story, and you might as well let me in. You will, you know, so why quibble about it? At least, you always have ... or do ... or will. I don't know, verbs get all mixed up. We don't have the right attitude toward tenses for a situation like this. Anyhow, you'll let me in. I did, so you will. Thanks. You think you're crazy, of course, but you'll find out you sense things. So I'll simply go ahead talking for half an hour or so, until you get over it. After that you'll come along with me. You know, I could try to change things around by telling what happened to me but he—I—told me what I was going to do, so I might as well do the same. I probably couldn't help telling you the same thing in the same words, even if I tried—and I don't intend to try. I've gotten past that stage in worrying about all this. So let's begin when you get up in half an hour and come out with me. obvious it must be a time machine. You'll sense that, too. You've seen and you'll be getting used to the idea that you are the man who makes you'll want to go along. I'll be tired of talking by then, and in a hurry to get going. So I isn't protected, though. You start to say something, but by then I'm pressing a black button, and everything outside will disappear. You look for your house, but turns over and pokes back at you. Doesn't hurt, and when you pull your arm back, you're still sound and uninjured. But it looks frightening and you don't try it again. Then you feel silly, because you'll remember that I said you'd ask the machine and I don't understand it." "But...." I let it go, and so do you. If you don't, it's a good way of going crazy. You'll see later why I couldn't have invented the machine. Of saving yourself the trouble, it got all tangled up. I figured out once pretty easygoing civilization, from what I could see. We'll go up and I'll leave you. I like the looks of things here, so I won't be coming back with you." I'd told you that, too, but you've forgotten. "As near as I can guess, "What about the time machine?" you ask. nobody around. I grab your hand and shake it. "You go that way. Don't worry about getting lost you never did, so you can't. Find the museum, grab the motor, and get out. And good luck to you." You act as if you're dreaming, though you can't believe it's a dream. You nod at me and I move out into the main corridor. A second later, questions of a man, who points, and I turn and move off. the hang of the spelling they use, though. Now there are people around you, but nobody pays much attention to you. Why should they? You wouldn't care if you saw a man in a leopard-skin suit you'd figure it was some part in a play and let it go. Well, people don't change much. You get up your courage and go up to a boy selling something that might be papers on tapes. "Downayer rien turn lefa the sign. Stoo bloss," he tells you. Around you, you hear some pretty normal English, but there are others using stuff as garbled as his. The educated and uneducated? I don't know. hesitate for a moment, then. You're beginning to think the whole affair is complete nonsense, and you should get back to the time machine and go home. But then a guard comes to the gate. Except for the short legs in his suit and the friendly grin on his face, he looks like any other guard. He beams at that. "Of course." The gate is swung to behind you, but obviously he isn't locking it. In fact, there doesn't seem to be a Oh—congratulations on your pronunciation. Sounds just like some of our oldest tapes." You get away from him, finally, after some polite thanks. The building seems deserted and you wander up the stairs. There's a room on your his name. Either they don't know it, or they take it for granted that everyone does, which seems more probable. They call attention to the each side. "Nice," the guard says over your shoulder. "It finally wore out one of Like to have me tell you about it?" "Not particularly," you begin, and then realize bad manners might be conspicuous here. While you're searching for an answer, the guard pulls You work down the line. It'd be foolish to take the early model if you probably bolted down, too, but you try it tentatively and you find it moves. There's a little sign under it, indicating you shouldn't touch it, since the gravostatic plate is being renewed. after he told me, but I can't be sure. So I'll keep on talking. I probably can't help it, anyhow. Pre-set, you might say. Well, you stagger down the corridor, looking out for the guard, but all seems clear. Then you hear his voice from the weapons room. You bend down and try to scurry past, but you know you're in full view. Nothing happens, though. is closed. You reach it and it opens obligingly by itself. You breathe a quick sigh of relief and start out onto the street. Then there's a yell behind you. You don't wait. You put one leg in front of the other and you begin racing down the walk, ducking past people, who stare at you with expressions you haven't time to see. of your feet, with a sudden ringing sound. You don't wait to find out about that, either. Somebody reaches out a hand to catch you and you dart past. The street is pretty clear now and you jolt along, with your arms Out of nowhere, something in a blue uniform about six feet tall and on the beefy side appears—and the badge hasn't changed much. The cop catches your arm and you know you're not going to get away, so you stop. "You can't exert yourself that hard in this heat, fellow," the cop says. "There are laws against that, without a yellow sticker. Here, let out and taps a pedestrian lightly on the shoulder. "Sir, an emergency The pedestrian grins, looks at his watch, and nods. "How far?" mutter it. The stranger nods again, reaches out and picks up the other Pedestrians begin to move aside, and you and the stranger jog down the here doesn't look too good. The guard can get the same and be there before you. And he is. He stands just inside the door of the building as you reach it. The stranger lifts an eyebrow and goes off at once when you nod dissimilar in other ways. He snaps it open and you get set to duck. "You forgot the prints, monograph, and patent applications," he says. we'll pick it up." You swallow several sets of tonsils you had removed years before, and you for some more information, which you give him at random. It seems to satisfy your amiable guard friend. He finally smiles in satisfaction and heads back to the museum. You'll never know what the shouting was about—whether they finally doped out the fact that they'd been robbed, or whether they were trying to help you. You don't care which it is. The field springs up around you and the next button you touch—the one on the board that hasn't been used so far—sends you off into nothingness. There is no beam of light, you can't hear a thing, and you're safe. in time, somehow, and is back to its original youth—minus the kids from school are coming around to stare at the man who changed view—and telling your younger self all these things I'm telling you. without protest, and I want to find out just why those people up there came looking for you and shouting, before the time machine left. Let's go.
