But my quibble is that I don't think Hemingway valued efficiency. It would be much more efficient to write "There was a man in the hospital who had lost his reproductive organs and this resulted in a tragically failed romance" but that is not how he wrote the story, because it's bad literature. But if someone at work asked me to write them an email about it, that's what I would write, because it's much more efficient than a whole novel.
