Chekhov Gun discussions always remind me of this Vonnegut passage:
"I had no respect whatsoever for the creative works of either the painter or the novelist. I thought Karabekian with his meaningless pictures had entered into a conspiracy with millionaires to make poor people feel stupid. I thought Beatrice Keedsler had joined hands with other old-fashioned storytellers to make people believe that life had leading characters, minor characters, significant details, insignificant details, that it had lessons to be learned, tests to be passed, and a beginning, a middle, and an end.
"As I approached my fiftieth birthday, I had become more and more enraged and mystified by the idiot decisions made by my countrymen. And then I had come suddenly to pity them, for I understood how innocent and natural it was for them to behave so abominably, and with such abominable results: They were doing their best to live like people invented in story books. This was the reason Americans shot each other so often: It was a convenient literary device for ending short stories and books."
(from Breakfast of Champions, by an author who often tells you the end in the beginning and puts the journey in the details)
