Suddenly I couldn't remember whether Ganymede was Jupiter's third moon or fourth. And I just had to know. There was a book out in the living room that would tell and more besides—Ellsworth Smith's A Tour of Earth's Colonies. I went out to get it.

Dad hadn't gone to bed. He was sitting up, reading. I said, "Oh—hello," and went to look for the book. He nodded and went on reading.

The book wasn't where it should have been. I looked around and Dad said, "What are you looking for, Bill?"

Then I saw that he was reading it. I said, "Oh, nothing. I didn't know you were using it."

"This?" He held it up.

"It doesn't matter. I'll find something else."

"Take it. I'm through with it."

"Well ... All right-thanks." I took it and turned away.

"Just a minute, Bill."

I waited. "I've come to a decision, Bill. I'm not going."

"Huh?"

"You were right about us being partners. My place is here."

"Yes, but— Look, George, I'm sorry I said what I did about rations. I know that's not the reason. The reason is—well, you've got to go." I wanted to tell him I knew the reason was Anne, but if I said Anne's name out loud I was afraid I'd bawl.

"You mean that you are willing to stay behind—and go to school?"

"Uh—" I wasn't quite ready to say that; I was dead set on going myself. "I didn't quite mean that. I meant that I know why you want to go, why you've got to go."

"Hmm..." He lit his pipe, making a long business of it. "I see. Or maybe I don't" Then he added, "Let's put it this way, Bill. The partnership stands. Either we both go, or we both stay—unless you decide of your own volition that you will stay to get your degree and join me out there later. Is that fair?"
