Yesterday, while I was writing, I discovered one of my characters had done something terrible. I didn't know he was capable of it, but there it was. I was so happy. I couldn't have planned it, didn't see it coming until I started writing. I wish I understood the process my mind uses, but I can't. This stuff just emerges without rhyme or reason. I suppose my brain uses an impulse pattern when writing. I'm a pretty staid and stable person, rarely given to fits of impulse, so I imagine writing is an outlet for that "wilder" side of me I keep under control.
