<passage>:
It was just one of those days. Everybody gets them. Days when you're lucky in you make it to nightfall with no bones broken. But of all times for it to happen! For literally months I'd been building my courage up. And finally, just today, I had made up my again. "Now, then," he said. "If you know it doesn't make any sense for this Project to attack any other project, then why in the world should you think waited for it. They simply knew that it had been captured by some other Project and had blown itself up. they ?" I shook my head, dumbfounded. "I can't answer a question like that," I said. "How do I know what they're thinking?" "They're human beings, aren't they?" he cried. "Like you? Like me? Like all the other people in this mausoleum?" shortly after we'd started dating, when I arrived at her place five minutes late and found her having hysterics. She thought I'd been killed. She couldn't visualize anything less than that keeping me from arriving at the designated moment. When I told her what actually had happened—I'd broken a shoe lace—she refused to speak to me for four Until then, I'd managed somehow to keep the day's minor disasters from ruining my mood. Even while eating that horrible egg—I couldn't very well throw it away, broken yolk or no days. for any kind of marriage other than Non-P—Non-Permanent, No Progeny. So I rehearsed my various approaches, realizing that when the time came I would probably be so tongue-tied I'd be capable of no more how much radiation had been released by the Atom War. But I wanted to test the theory, and the Commission wouldn't let me. They claimed public safety, but I knew better. If the Outside were safe and the Projects were no longer needed, then the Commission was out of a job, radiation Outside was lessening by now, though we had no idea exactly and they knew it. would come after all? Or hurry back to the apartment and call Linda, to give her advance warning that I would be late? No matter. It didn't arrive. I would have been in a howling rage anyway, but this impossibility piled on top of all the other annoyances and breakdowns of the day any attention to. "We're not supposed to give this information out, sir," she said, her voice low, "but I'm going to tell you, so you'll understand why we had to do it. I think it's perfectly awful that it hardly help but take note of her cleavage. She whispered, "They're afraid they'll have to starve him out." "Oh, no!" "We-will-resume-service-as-soon-as-possible." Click. Blank screen. For a minute or two, all I could do was sit and absorb what I'd been What in the world was the matter with the Army? If things were getting that lax, the Project was doomed, force-screen or no. Who knew how many more spies there were in the Project, still unsuspected? Until that moment, the state of siege in which we all lived had had no reality for me. The Project, after all, was self-sufficient and completely enclosed. No one ever left, no one ever entered. Under our return, occasional spies shot down as they tried to sneak into the building, occasional spies of our own leaving the Project in tiny radiation-proof cars, hoping to get safely within another project and bring back news of any immediate threats and dangers that project might be planning for us. Most spies didn't return within the Project life was full, the knowledge of external dangers merely lurking at the backs of our minds. After all, those external dangers had been no more than potential for decades, since what Dr. Kilbillie called the Ungentlemanly Gentleman's War. everybody lived in Projects. From the very beginning, small attempts were made to make these Projects more than dwelling places. By mid-century, Projects Projects themselves and so on. And all because of, among other things, the population explosion. nations (they were something like Projects, only horizontal instead of vertical) and both sets were equipped with atomic weapons. The Treaty of Oslo began by stating that atomic war was unthinkable, and added did think of the war, both sides adhered to the Treaty of Oslo, which meant that no Projects were bombed. Of course, they made up for this as best they could by using tactical atomic weapons all over the place. After the war almost the whole which had been invented on the very eve of battle, and which deflected radioactive particles. However, what with all of the they weren't sure either, it was risky to expose yourself in order to ask. And so life went on, with little to remind us of the dangers lurking Outside. The basic policy of Eternal Vigilance and Instant Preparedness was left to the Army. The rest of us simply lived our lives and let it go at that. I hadn't paid any attention to it before. No one ever uses the stairs except adventurous young boys playing cops and robbers, running up and down from landing to landing. I myself hadn't set foot on a flight of stairs since I was twelve years old. If the door would open. It would, though reluctantly. Who knew how many years it had been since last this door had been opened? It squeaked and wailed and groaned and answers flashed through my mind. The more recent maps might simply have omitted this discarded and unnecessary door. It might be sealed shut on the other side. The Army might have caught the spy already. came face to face like that. We formed a brief tableau, both of us open-mouthed and wide-eyed. said, "Don't try it. I don't want to kill you. I don't want to kill anybody, but I will if I have to. We'll just wait here together until ever going to get to her place. By now she was probably in mourning for me I had no idea what he was talking about, and admitted as much. "When they come back," he said. "How much radiation do they pick up? Don't you people ever test them?" "I know that," he said impatiently. "But don't you ever check them before de-radiating them?" "No. Why should we?" "To find out how far the radiation level outside has dropped." "For what? Who cares about that?" He frowned bitterly. "The same answer," he muttered, more to himself than to me. "The same answer every time. You people have crawled into your caves and you're ready to stay in them forever." I looked around at my apartment. "Rather a well-appointed cave," I told a fanatical flame. "Don't you ever wish to get Outside?" Incredible! I nearly poured boiling water all over myself. "Outside? Of course not!" "The same thing," he grumbled, "over and over again. Always the same stupidity. Listen, you! Do you realize how long it took man to get out of the caves? The long slow painful creep of progress, for millennia, before he ever made that first step from the cave?" "I have no idea," I told him. growing up. His dreams were getting bigger and grander and better all the time. He was planning to tackle space suddenly said, "What did they tell you I was? A spy?" "Of course," I said. He asked the question so violently and urgently that I knew I had to answer quickly and well, or the maniac would return. "I—I wouldn't "Your people send out spies, too, don't they?" he demanded. "Well, of course." they supposed to spy on?" "Well—" It was such a pointless question, it seemed silly to even answer it. "They're supposed to look for indications of an attack by one of the other projects." "And do they find any indications, ever?" "I'm sure I don't know," I told him frostily. "That would be classified information."
