Despite an earlier post claiming a lack of obligation to explain the links between my fiction and my real life, I’m willing to cop to certain overlaps between the two. They involve physical settings.
My thoughts on using actual settings isn’t so much that the imagination can’t take the place of reality (I believe it can), but that using settings personally familiar to a writer creates an obligation to create a “morally” responsible narrative. “Writing what you know” makes sense not only because you’ll have a handle on the details, but because you’ll have an emotional anchor for the entire scene or story.
If I use my local laundromat, which I’ve been patronizing for more than a decade, as a central point for a story, I know I’ll treat the story with respect because I don’t want to trivialize a place with which I have an emotional, not to mention domestic, bond. Call it exploiting those places and objects by letting your feelings for them bleed into the narrative you’re building around them. It’s safer and easier to do this with places and things than with friends and lovers.
