Fortunately this was the easiest part. She went to the screen and began to alter it. It could be made to scan what the gravity computer passed on to the geepee heads. A row of dominos, each of which would topple if the first were struck, and the screen was the last of the series. "Hello," said a voice. "So this is where you always are. What a dreary place to work." She didn't hear the voice. She felt the footsteps and the air brushing against her skin. She turned around, letting her hands continue, deft and sure. She didn't need to see what she was doing. The smile was involuntary. He leaned against the wall, watching her. It was embarrassing the way she gazed back. He wished she could say something but then he'd always wished it. He'd had a thesis once, hadn't he? that for mechanics deafness wasn't a handicap considering how noisy machines were. A deaf person could withstand a concentration of sound the average man would find intolerable. And there was no need for such a person to talk since there was no one who could hear. The connections in her hands grew swiftly. She felt that she could work better while he was near. Why was this? "What do you respond to?" he said gruffly. "Diagrams, blue-prints? If so I'll have to learn to draw the damnedest things." He laughed uncertainly. "Come on, help me a little bit. I've got some ideas that might help you break out of your shell if you'd try to respond." He fixed things too, warm soft mechanisms. She didn't know but she thought it was a higher skill than hers. He was not as adept as she was, though he could learn to be. There was so much more he could do if he would realize. His mouth was a handicap. He moved it often when he should be thinking. "Listen, robot face, I left a career for you. Do you think they wouldn't take me back? The Medicouncil wouldn't like it but I'd have been a popular hero. Sometimes they want their heroes to fail. Besides from their viewpoint it was the best possible solution. Now they don't have to think of people like you out on that god-forsaken asteroid. You're off their conscience and they don't have to have bad dreams about you." She smiled again and it was infuriating. What he said or did had no effect. "At least show that you recognize me. Stop what you're doing. It can't be important." He drew her to him roughly and the work fell from her hands. The connections had been done minutes before and she'd continued to hold them because she didn't want to move away from him. She was willing to let him look at her closely if he wanted. It was surprising how much he wanted to. Later he held her away from him. "I take it back," he said softly. "You're not a robot face. There's no point of resemblance to a machine. And look, you've even discovered that you've got more than one expression." The robot aide that had been laboring on whirred inaudibly and clacked its extensibles. It rolled away from the work bench, brushing lightly against the doctor as it did so.
