Now, Siebling thought, he would be obliged to talk to it, and he feared that he would lose the good opinion which it had somehow acquired of him. He was in a position strangely like that of a young girl who would have liked nothing better than to talk of her dresses and her boy friends to someone with her own background, and was forced to endure a brilliant and witty conversation with some man three times her age.

But he lost some of his awe when he faced the Sack itself. It would have been absurd to say that the strange creature’s manner put him at ease. The creature had no manner. It was featureless and expressionless, and even when part of it moved, as when it was speaking, the effect was completely impersonal. Nevertheless, something about it did make him lose his fears.

For a time he stood before it and said nothing. To his surprise, the Sack spoke—the first time to his knowledge that it had done so without being asked a question. “You will not disappoint me,” it said. “I expect nothing.”

Siebling grinned. Not only had the Sack never before volunteered to speak, it had never spoken so dryly. For the first time it began to seem not so much a mechanical brain as the living creature he knew it to be. He asked, “Has anyone ever before asked you about your origin?”

“One man. That was before my time was rationed. And even he caught himself when he realized that he might better be asking how to become rich, and he paid little attention to my answer.”

“How old are you?”

“Four hundred thousand years. I can tell you to the fraction of a second, but I suppose that you do not wish me to speak as precisely as usual.”

The thing, thought Siebling, did have in its way a sense of humor. “How much of that time,” he asked, “have you spent alone?”

“More than ten thousand years.”

“You told someone once that your companions were killed by meteors. Couldn’t you have guarded against them?”
