Elizabeth's discussion on 'voice' lead me to think of a related question:
Does anyone else worry sometimes that they might leaking too much of their unconscious onto the page through their writer's voice?
Critics love to analyse writers and filmmakers for recurring themes in their work - Hitchcock's obsession with the cool blonde, for example. I've noticed the link between memory and identity cropping up in a few of my stories, but maybe I've also accidentally aired some skeletons in my subconscious closet (don't worry, there's nothing bigger than a squirrel skeleton in there).
Are the ideas behind your stories always planned or have you spotted underlying themes cropping up of their own accord?
