I grew up in a house full of books. None were off limits. Also, paintings on the walls. This was my mother's house. In my father's house, where I was required very much against my will to spend alternate weekends, my step-mother had a big collection of (presumably valuable) books that I was not permitted to touch. I always thought there was something deeply wrong with the idea of not being allowed to read a book. That's what they're for. What would Charles Dickens have thought about a person who bought one of his books, and then would not allow a child to read it?
