I used to write things for friends. There was this girl I had a crush on and she had a teacher she didn't like at school. I had a real crush on her so almost every day I would write her a little short story where she would kill him in a different way.
I also think the relationship I have with my audience is a lot more complex than what Hitchcock seemed to want his to be - although I think he had more going on under the surface as well.
