I love surprises.
Good ones, I mean.
I'm working on a new manuscript, and I'm getting plenty of them. Characters I'd envisioned one way are showing me their real lives. You might say their lives are a little different from what I thought initially. And for the better.
At least no one has laughed at me yet. That happened one time. About 50 pages in, my protagonist told me she'd given me a fake name. Her real name was entirely different. After I made the changes, she shaped up and stopped giving me trouble.
Characters are like that.
