I'm pretty sure he interpreted it as an indication that I was trying to catch him up on something he took pride in, and he admired me for it, and greeted me with a chuckle.

"Well, Ralph!" he said. "I didn't expect to see you here tonight. I thought you'd be home wearing Joan's patience ragged with the kind of last-minute preparations women never seem to understand. They like to think they never forget anything. But they do. They're worse that way than we are, but just try getting them to admit it."

There was only one chair in the office and he was occupying it. I hardly expected him to get up and wave me toward it, but that's precisely what he did.

"Sit down, Ralph," he said. "I sit too much. We all do here, I guess. Can't be helped, but it doesn't give a man of fifty-five much chance to get the exercise he ought to have, if he's going to keep his weight down."

"No—don't get up for me, sir!" I said, then realized I was being unnecessarily formal.

The chair was empty and he expected me to take it. And I could see that he didn't like the "sir." He never had.

"Sit down, sit down. What is it, Ralph? Something worrying you? You'll have plenty of time for that when you get to Mars. Why start now?"

I decided to come right out with it. I favored bluntness as much as he did, and there was nothing to be gained by talking around what I'd have to ask him before I left.

"There's something I'd like to know," I said. "Is the major part of my assignment still under wraps, or could you tell me more about it—even if you'd prefer not to?"

He looked at me steadily for a moment, his lips tightening a little. "Well—I certainly haven't kept it a complete secret, Ralph. You'll get full instructions in code later on. There's naturally a reason for that. I shouldn't have to go into it, because we've discussed it at great length right here in this office."
