Talking with yourself

Do you ever find yourself having a conversation with a made up character or a real person, with yourself. Like you are practicing what to say or how it should be said. I do all the time. If it is for a real person it is called practicing. With a character it is called figuring. The other day I found myself in the shower explaining to myself the life history of one of my characters that will one day be in a book. The next thing I knew I found myself with notebook in hand writing all of her background story down, because in dialogue form I had figured it out. Which I could not have done if I had sat down with said notebook and said okay lets figure out her history. It was better the other way, more spontaneous and in a way more fun. But the down side is sometimes we don't have to time to wait for those funny conversations, where we can figure out the life history of a character. But it makes it so fun when we can!
