He closed his hand on her wrist and twisted it away. "What else?" he demanded, trying to imagine how it would feel to stay reasonable for five minutes at a time with these Bridge robots. "None of us need bother with games and excuses. We're here, we're isolated; we were all chosen because, among other things, we were quite incapable of forming permanent emotional attachments and capable of any alliances we liked without going unbalanced when the attraction died and the alliance came unstuck. None of us have to pretend that our living arrangements would keep us out of jail in Boston, or that they have to involve any Earth normal excuses."

She said nothing. After a while he asked, gently: "Isn't that so?"

"Of course it's not so," Eva said. She was frowning at him; he had the absurd impression that she was pitying him. "If we were really incapable of making any permanent attachment, we'd never have been chosen. A cast of mind like that is a mental disease, Bob; it's anti-survival from the ground up. It's the conditioning that made us this way. Didn't you know?"

Helmuth hadn't known; or if he had, he had been conditioned to forget it. He gripped the arms of the chair tighter.

"Anyhow," he said, "that's the way we are."

"Yes,, it is. Also it has nothing to do with the matter."

"It doesn't? How stupid do you think I am? I don't care whether or not you've decided to have a child here, if you really mean what you say."

She, too, seemed to be trembling. "You really don't, either. The decision means nothing to you."

"Well, if I liked children, I'd be sorry for the child. But as it happens, I can't stand children and if that's the conditioning, too, I can't do a thing about it. In short, Eva, as far as I'm concerned you can have as many kids as you want, and to me you'll still be the worst operator on the Bridge."

"I'll bear that in mind," she said. At this moment she seemed to have been cut from pressure ice. "I'll leave you something to charge your mind with, too, Robert Helmuth. I'll leave you sprawled here under your precious book what is Madame Bovary to you, anyhow, you unadventurous turtle? ... to think about a man who believes that children must always be born into warm cradles a man who thinks that men have to huddle on warm worlds, or they won't survive. A man with no ears, no eyes, scarcely any head. A man in terror, a man crying: Mamma! Mamma! all the stellar days and nights long!"

"Parlor diagnosis."

"Parlor labeling! Good trick, Bob. Draw your warm woolly blanket in tight around your brains, or some little sneeze of sense might creep in, and impair your efficiency!"

The door closed sharply after her.
