" " To his left, on the wall, he caught kaleidoscopic glimpses of Mom's old bothered to smooth her clipped, creamy-brown hair as she always did become a hostile stranger with narrowed eyes of black fire.

"Maybe it's my own fault. house in Washington instead of trying to commute." "David," said Mom, very seriously, almost as if she were praying, "it won't be necessary to have him memory-washed, will it?" "And you can't get ahead if people know you've been a Reader. That's something you can't live down. No matter how hard you try, people always stumble upon the truth." Dad cleared his throat. "You see, when you get a job, all the information you handle will have a classification. It'll be Restricted, Low-Confidential, Confidential, High-Confidential, Secret, Top-Secret. And all this information will be in writing. No matter what you do, you'll have access to some of this information at one time or another." might have access to could describe secret weapons and new processes or plans for next year's advertising—maybe even a scheme for, er, liquidation of a rival. If all facts and policies were made public, there might be criticism, controversy, opposition by certain groups. The less people know about things, the better. So we have to keep all these things secret." "Sure, son. One person in ten thousand might reach the point where his corporation or bureau will teach him to read. But you prove your ability and loyalty first. By the time you're 35 or 40, they might want you to learn to read. But for young people and children—well, it just isn't done. Why, the President himself wasn't trusted to learn Top -Secret stuff. And who knows? Maybe by the time I'm 50 I'll be giving orders instead of carrying them. Then I'll learn to read, too. That's the right way to do it." and—" "Damn it, son, how could you even a life-sized, 3-D video here, and we put on the smell and touch and heat attachments just for you. You can listen to any tape in the world "B—but, Daddy—" this boy in a reformatory. Maybe a good memory-wash will take some of the nonsense out of him!" Ronnie suppressed a sob. "No, Daddy, don't let them take away my brain. Please—" Dad stood very tall and very stiff, not even looking at him. "They won't take your brain, just your memory for the past two years." A corner of Mom's mouth twitched. "David, I didn't want anything like this. I thought maybe Ronnie could have a few private psychiatric treatments. They can do wonderful things now—permi-hypnosis, creations of artificial psychic blocks. A memory-wash would mean that Ronnie'd have the mind of a six-year-old child again. He'd have to start to school all over again." know what to do." He looked up abruptly, as if struck by a chilling new thought. "You can't keep a two-year memory-wash a secret. I never thought of that before. Why, that alone would mean the end of my promotions." Silence settled over the room, punctuated only by the ticking of the antique clock. All movement seemed frozen, as if the room lay at the "David," Mom finally said. "Yes?" "There's only one solution. We can't destroy two years of Ronnie's memory—you said that yourself. So we'll have to take him to a psychiatrist or maybe a psychoneurologist. A few short treatments—" Dad interrupted: "But he'd still remember how to read, unconsciously anyway.

Mom went to a mahogany chest in the dining room, produced three faded touching a rotting corpse. "Old," he mused, "—so very old. Ironic, isn't it? Our lives are being wrecked by things that should have been destroyed and forgotten a hundred years ago." A sudden frown contorted his dark features. Tick-de-tock, tick-de-tock "A hundred years old," he repeated. His mouth became a hard, thin line. Dad nodded at the clock, and the slow, smouldering anger returned to his face. "It's your fault, Edith. You've always liked old things. That clock of your great-great-grandmother's. Those old prints on the wall. That stamp collection you started for Ronnie—stamps dated way back to the 1940's." years, in a pleasant house, these things symbolize peace and security. just too stupid to realize it." Mom whispered hoarsely, "I'm sorry, David." Hot anger flashed in Dad's eyes. "It isn't enough to be sorry. Don't you see what this means? Ronnie'll have to be memory-washed back to the time of birth. He'll have to start life all over again." "No, David, no!" the mind of a new-born baby. It's got to be Abandonment, Edith, there's no other way.

I've never told anyone—not even Ronnie. I haven't read a book, haven't even looked at one since we were married. I've "You lied to me," Dad snapped. "For ten years you've lied to me. Why " think. And there are beautiful words and beautiful thoughts, just like there are beautiful paintings. It isn't enough just to hear them and then forget them. Sometimes you want to keep the words and thoughts before you because in that way you feel that they belong to you." Her words echoed in the room until absorbed by the ceaseless, ticking At last he said, "Get out." Mom stared blankly. "Get out. Both of you. You can send for your things later. I never want to see either of you again." "David—" "I said get out !" the town behind them. They stumbled over a rough, dirt country road.
