To me, the writer's main job is to just make the story unscroll in such a way that the reader is snared - she's right there, seeing things happen and caring about them. And if you dedicate yourself to this job, the meanings more or less take care of themselves. That's the theory, anyway.
To whom, then, must I dedicate my wonderful, surprising and interesting adventures? to whom dare I reveal my private opinion of my nearest relations? the secret thoughts of my dearest friends? my own hopes, fears, reflections and dislikes? Nobody!
