As a kid I steadily worked my way through my Dad's extensive collection of books that were for some unknown reason kept in the garage (I suspect they simply never got unpacked after a move). I read all his sci-fi books and westerns going from Asimov to Zane Grey. I was never told not read them but, as per the Dracula story above, there were some I'm sure I wasn't supposed to be reading. I also read all my mom's anthropology / sociology / psychology books - Ascent of Man, Tao of Pooh, and some feminist literature. I didn't always understand everything in them .... but I read them. Now that I think about it it was kind of weird, we had all these books but I don't remember ever once talking to my parents about any of the ideas in them.
