"Children!" my mother protested, distressed. "I'm afraid you've picked up some really unpleasant concepts from those dreadful natives."
"Come, come, Qana," Grandfather ideated, "we mustn't be intolerant."
"Perhaps not," she replied with heat, "and I know the natives probably don't know any better, but I am not going to have my young one or anyone else's contaminated. Visit the third planet if you wish, but not this time. You'll have to make a special trip for it. I'm not going to let you stop off there while the young ones are aboard. It's obviously no fit place for children."
