It's horribly frustrating when your characters become so human that you find out you didn't know them as well as you thought. But it makes you think, too. All my first impressions of these characters are turning out to be wrong. And, uncomfortably, it's the same kinds of misconceptions that I tend to make in real life. There's a whole lot more to people than we can see on the surface. And if this is the only thing I get out all this work on my writing, I'll be satisfied.
