To most readers the word 'fiction' is an utter fraud. They are entirely convinced that each character has an exact counterpart in real life and that any small discrepancy with that counterpart is a simple error on the author's part. Consequently, they are totally at a loss if anything essential is altered. Make Abraham Lincoln a dentist, put the Gettysburg Address on his tongue, and nobody will recognize it.
It's very rare that a character comes to mind complete in himself. He needs additional traits that I often pick from actual people. One way you can cover your tracks is to change the sex.
I don't particularly care about having [my characters] talk realistically, that doesn't mean very much to me. Actually, a lot of people speak more articulately than some critics think, but before the 20th century it really didn't occur to many writers that their language had to be the language of everyday speech. When Wordsworth first considered that in poetry, it was considered very much of a shocker. And although I'm delighted to have things in ordinary speech, it's not what I'm trying to perform myself at all: I want my characters to get their ideas across, and I want them to be articulate.
