"Acrophilia," I said.

"True. Baptizing a thing doesn't explain it, though. I never understood why I did it. Still don't, for that matter. I did finally stop it for a long while, though. Middle-age hormone shift perhaps. Who knows? Then I came here to teach. It was when I heard of your own activities that I began thinking about it again. This led to the desire, the act, the return of the compulsion.

He took another drink, offered me one. I would have liked to but I know my limits, and sitting there on the ledge, I was not about to push them. So he gestured with the bottle, skyward, then: "To the lady with the smile," he said, and drank it for me.

"To the rocks of empire," he added a moment later, with a swing and a swig to another starry sector. The wrong one, but no matter. He knew as well as I that it was still below the horizon.

He settled back, found a cigar, lit it, mused: "How many eyes per head, I wonder, in the place they regard the ‘Mona Lisa'? Are they faceted? Fixed? And of what color?"

"Only two. You know that. And sort of hazel-in the pictures, anyway."

"Must you deflate romantic rhetoric? Besides, the Astabigans have plenty of visitors from other worlds who will be viewing her."

"True. And for that matter, the British Crown Jewels are in the custody of people with crescent-shaped pupils. Kind of lavender-eyed, I believe."

"Sufficient," he said. "Redeeming. Thank you."

A shooting star burned its way earthward. My cigarette butt followed it.
