At least that's what Mrs. Bates always told Norman.
I rememebr the first time I ever saw Psycho, it as a sunny Saturday afternoon when I was about 12. That it was the afternoon is significant, because it cut down dramatically on the terror and suspense which characterizes the film. It's hard to be creeped out when the sun is shining and birds are chirping and your mother's in the kitchen cleaning with Pine Sol. And while I didn't find the movie to be particularly terrifying, it was creepy, especially Norman's man-boy schtick and his creepy semi-sexual relationship with his mother. You don't have to be a Jungian psychoanlyst to know that their relationship was simply not healthy. She was controlling, he was dependent. In a word, they were too close.
In this era of helicopter parenting, folks sometimes have a hard time distinguishing where their needs end and their children's begin. Let the Bates family serve as a cautionary tale. Don't think it's possible to be "too close" with your child? Well, then, please watch this: http://www.youtube.com/watch?v=U8CGFF3rlSo&feature=related
