course, he didn't really care; if his wife or Kelly's had been responsible, it was all the more reason to feel appreciated. Nob knew the answer, but he had other things on his mind. He lay awake, restless, until his wife asked worriedly what was wrong. "I've been wondering," he said. "Those war books that the Earthmen had us turn in—I never did understand why all those deletions were made. You know, the ones that made us figure out a way of deciding which side won." "But the Earthmen said they used the very same system," she reminded him. "And they wouldn't lie, would they?" "They would, if it was for our good. That's what is known as diplomacy, dear. Statesmanship. Or politics. Interchangeable terms." She looked impressed. "Oh. And?" "I've tried to question the crews of ships that land here. The answers are so evasive that I can't help thinking—" "Yes, dear?" she prompted. "—that civilized people actually kill each other in wars." She turned a shocked face toward him. "How can you think such a thing? What would be the advantage?" "Advantage?" he repeated. Then his expression cleared and he fell back on his pillow, completely relaxed. "I hadn't thought of that, dear. None, of course. It would really be too much, wouldn't it?" "No question of it, dear," she said. "Now that that's settled, can you go to sleep?" There was no answer. He was already snoring peacefully.
