The characters who go to make up my stories and novels are not portraits. Characters I invent along with the story that carries them. Attached to them are what I've borrowed, perhaps unconsciously, bit by bit, of persons I have seen or noticed or remembered in the flesh - a cast of countenance here, a manner of walking there, that jumps to the visualizing mind when a story is under way. I don't write by invasion into the life of a real person: my own sense of privacy is too strong for that; and I also know instinctively that living people to whom you are close - those known to you in ways too deep, too overflowing, ever to be plumbed outside love - do not yield to, could never fit into, the demands of a story. Characters take on life sometimes by luck, but I suspect it is when you can write most entirely out of yourself, that a character becomes in its own right another human being on the page.
