One of my favorite aspects of novel writing is experiencing those moments when my characters come into their own - assuming lives seemingly independent of me - and begin doing and saying all manner of unexpected things.
At times like these I get the feeling that I'm dabbling in something deeper than what I can understand, and all I can do is play referee on the sidelines and watch as the drama unfolds.
Obviously the problem here lies in trying to maintain some kind of order and structure. I took a writing class a couple years ago in which the teacher described a phenomenon that happens towards the end of many a (hopeful) novel. Suddenly hitherto-minor characters start taking a much more active role in the story and the writer wallows in page upon page of diversive material when he or she should be ploughing ahead to the climax and resolution.
She suggested having some dialogue with these characters at this point, and basically asking, "Do you need a novel of your own, then, so your story can be told, or do you just need to pipe down?"
Pulling in the reins on our characters
My old teacher summed up the average writer's tendency to indulge by saying: "I've rarely read I novel that I didn't feel could've been improved by a cut of a hundred pages."
