"I won't. You can't make me take my place. My father is the Mayor." The metal voice carried no feeling. "If you do not take your place you will be punished." "You can't lay a hand on me. No robot can." The robot moved forward. Two metal hands held Johnny Malone. Johnny Malone kicked the robot's legs. It hurt his toes. "We were made to teach the children. We can do what is necessary to teach the children. I will do everything for the children's good. It is my prime law. All other laws are secondary to the children's good." The metal arms moved. The human body bent across metal knees. A metal hand raised and fell, flat, very flat so that it would sting and the blood would come rushing, and yet there would be no bruising, no damage to the human flesh. Johnny Malone cried out in surprise. Johnny Malone wept. Johnny Malone squirmed. The metal ignored all of these. Johnny Malone was placed on his feet. He swarmed against the robot, striking it with small fists, bruising them against the solid smoothness of the robot's thighs. "You will take your place, please." Tears were useless. Rage was useless. Metal cannot feel. Johnny Malone, the Mayor's son, was intelligent. He took his place in the classroom. One of the more advanced literature classes was reciting. The roboteacher said metallically, "The weird sisters, hand in hand, Posters of the sea and land, Thus do go about, about: Thrice to thine, and thrice to mine, And thrice again, to make up nine. Peace! the charm's wound up." Hands shot into the air. The metallic voice said, "Tom?" "That's from Shakespeare's Macbeth."
