"What's in your medicine cabinet? Your refrigerator? And your wallet?" I ask my new characters when they show up on the page. "Have you experienced grief, envy and joy? What makes you snort, or sneeze, or sigh?"
Once I know what a character does/feels/thinks, I can create all kinds of reasons why they choose those patterns.
I write pages and pages for each character's profile. I love this part of the discovery process. More than once I have learned that a character didn't belong in the story in which she first appeared. This is a great way for me to identify a ghost too - a character I very much want to exist, but one who just won't come. I know then I'm forcing a solution - perhaps walking too closely to a deux ex machina. And twice now I've had characters deliver the mcguffin in a play. Those experiences were a total surprise and so much fun!
Writing characters who listen to each other, or refuse to listen, is important to me. I can't do that unless I hear what they have to tell me. I have to listen to their "Who!"
