"This is a strange world," Foster said. "It will take me a long while to become accustomed to it."
"Yeah, me, too," I said. "Maybe things would be better on Mars."
Foster nodded. "Perhaps," he said. "Perhaps we should go there."
I groaned, then caught myself. "No, I'm not in pain," I said. "But don't take me so literally, Foster."
We rode along in silence for a while.
"Say, Foster," I said. "Have you still got that notebook of yours?"
Foster tried several pockets, came up with the book. He looked at it, turned it over, frowning.
"You remember it?" I said, watching him.
He shook his head slowly, then ran his finger around the circles embossed on the cover.
