I think it was published in Fantasy and Science Fiction magazine sometime in the 1960s. The basic idea that I remember was that a guy kept getting phone calls on a daily basis asking whether he could see the sun. Finally, there was a cloudy day where he told the caller that he couldn’t see the sun, at which he heard the caller say in the background to someone else, something like “It’s OK, he can’t see it, you can take it away now.”
Nope. I had the original F&SF magazine. I was quite young when I read it, and it sort of blew my mind at 11 years old. That’s probably why the story has stuck in my memory for so long.
I did remember it incorrectly, however; I had thought there were a series of calls in the story on succeeding days, until there was finally a day when the sun wasn’t visible. Actually, the story recounted only a single phone call. But it was the punchline that stuck in my head all these years.
