I imagine we'll get a lot of this; people seeing themselves in our characters, thinking they know who we're writing about. And they'll probably be right -- to a point. I think every character an author comes up with contains bits and pieces of the people in their lives. Then we take those bits and pieces, make them larger than life, and enhance the characteristics we need to make the story work. If we did our work correctly, the characater will come off as human, with strengths and frailties we can all recognize and empathize with. That's what makes a good character.
