I am not a native speaker,so I don´t understand at all all the ¨jokes¨about the style of Hemingway.What´s the problem?
If I'm remembering what you're talking about correctly, it's mainly that Hemingway would absolutely hate my writing. He never met a clause he couldn't turn into its own terse sentence, and the very idea of a dash or semicolon would offend his delicate sensibilities.
