SRS, you probably know the truth of this better than I but Mark Twain is reputed to have left home at 14, "amazed at how ignorant his father was" and not returning until he was 21, when he was "amazed at how much his father had learned."

And then there was the fridge magnet (mostly bought by parents) that suggested to adolescents that they leave home immediately so they could go and change the world while they still knew everything.
