Isaac Asimov tells about being in the audience at a talk about one of his stories (or at least when one of his stories came up). After the speaker gave his interpretation of the piece, Asimov got up and said he didn’t think that’s what the story meant.
“What makes you think you know what this story means?”
“I wrote it.”
“I still say, what makes you think you know what it means?”
[This is not Asimov’s verbatim account of the incident, just my no doubt faulty recollection. I’m sure someone – paging @Exapno_Mapcase – will recall it more accurately. I couldn’t find it in a few minutes of quick Googling.]
