So, simple answer, maybe. For some people, it might not be so simple. Who does the work in writing the story: the author (you) or your characters? I know for me its a mixed answer. My characters usually guide me, but I like to throw things at them once in a while. This usually happens after I've finished the story once, and I go back to add things. Then my characters and I get into a love-hate relationship, and they look up at me and give me the "oh come on! Really?" sort of deal. It might sound crazy to have a relationship with your characters, but I know I'm not the only one who feels that way.
