If you expect to succeed as a writer, rudeness should be the second-to-least of your concerns. The least of all should be polite society and what it expects. If you intend to write as truthfully as you can, your days as a member of polite society are numbered, anyway.
Stephen KingThe story is the only thing that's important. Everything else will take care of itself. It's like what bowlers say. You hear writers talk about character or theme or mood or mode or tense or person. But bowlers say, if you make the spares, the strikes will take care of themselves. If you can tell a story, everything else becomes possible. But without story, nothing is possible, because nobody wants to hear about your sensitive characters if there's nothing happening in the story. And the same is true with mood. Story is the only thing that's important.
