“At the universities, I suppose, though I wouldn’t know for sure. And you must realize that when I say no big cities, I also mean no little cities. We aren’t organized that way at all. I imagine the basic physical unit is the family and the circle of friends. Friends get important quickly, since the family breaks up when children are still relatively young. Something in the genes, I suppose—we all enjoy being alone. I suppose you might call it an inbred survival trait.”

“Up to a point,” she said, biting delicately into the apple. “Carry that sort of thing too far and you end up with no population at all. A certain amount of proximity is necessary for that.”

“Of course it is. And there must be some form of recognized relationship or control—that or complete promiscuity. On Anvhar the emphasis is on personal responsibility, and that seems to take care of the problem. If we didn’t have an adult way of looking at … things, our kind of life would be impossible. Individuals are brought together either by accident or design, and with this proximity must be some certainty of relations….”

“You’re losing me,” Lea protested. “Either I’m still foggy from the dope, or you are suddenly unable to speak a word of less than four syllables. You know—whenever this happens with you, I get the distinct impression that you are trying to cover up something. For Occam’s sake, be specific! Bring me together two of these hypothetical individuals and tell me what happens.”

Brion took a deep breath. He was in over his head and far from shore. “Well—take a bachelor like myself. Since I like cross-country skiing I make my home in this big house our family has, right at the edge of the Broken Hills. In summer I looked after a drumtum herd, but after slaughtering my time was my own all winter. I did a lot of skiing, and used to work for the Twenties. Sometimes I would go visiting. Then again, people would drop in on me—houses are few and far between on Anvhar. We don’t even have locks on our doors. You accept and give hospitality without qualification. Whoever comes. Male … female … in groups or just traveling alone….”

“I get the drift. Life must be dull for a single girl on your iceberg planet. She must surely have to stay home a lot.”

“Only if she wants to. Otherwise she can go wherever she wishes and be welcomed as another individual. I suppose it is out of fashion in the rest of the galaxy—and would probably raise a big laugh on Earth—but a platonic, disinterested friendship between man and woman is an accepted thing on Anvhar.”

“Sounds exceedingly dull. If you are all such cool and distant friends, how do babies get made?”
