I'm reminded of an amusing incident Asimov wrote about. He came across a large class where the teacher was discussing the meaning of one of Asimov's works. Asimov slipped in and sat in the back, and then afterwards went up to the teacher, introduced himself, and said that the interpretation was interesting but in several parts it was not what he had meant at all. The teacher replied, "Just because you wrote it, what makes you think you have the slightest idea what it's about?"
