I swear a lot in real life. I also can be vulgar. Sometimes that finds its way into my characters’ mouths and deeds. Sometimes that makes some pieces unfit for certain venues. When I think about censoring myself to please others I think of what Mark Twain wrote: “Substitute “damn” every time you’re inclined to write “very;” your editor will delete it and the writing will be just as it should be.”
Then again, I say more than damn.
