"What makes you surprised at finding that the sky is blue?" "Probably because I never saw it before. The only time I ever heard of its being anything other than green was when an engineer we have working for us at the factory said it was blue." "Well, never mind the sky. Let's find some place where we can get a little shelter for the night." She began to lead him slowly along an animal trail to a cluster of trees on a nearby stream. She walked with the obviously delayed pace one takes with invalids, but Hal had a difficult time keeping up. Finally, she said, "Here's a pretty good place. Sit down next to that tree. You must be worn out." "Oooo," he groaned, reclining back against a broad, rough oak trunk, then stiffening painfully away from it again. "It doesn't fit," he mourned plaintively. "Now you're sounding silly again," she scolded. "Go on, lean back. There aren't any suspend-field lounges out here for you, so you take what you get."

The woman stared at him with a tight frown between her eyebrows. Then she shook her head with wonder. "How you people can call yourselves civilized is beyond me. You yourself don't seem so bad, except that you don't have any guts. They've trained it all out by now." "Please," begged Hal. "You sound like that uncouth engineer that works for us. Impertinent." "That what engineer?" she demanded spiritedly. "Who are you, anyway?" "I'm Webber. Hal Webber. The engineer is a savage—oh sorry." He smiled weakly. "You're a savage, too. Guess you Outlanders don't regard yourselves as such." "No we don't," she snapped. "And if it weren't for us, you silly fools here on Earth would have died
