What was it that Granny Weatherwax had said once? "Evil starts when you begin to treat people as things". And right now it would happen if you thought there was a thing called a father, and a thing called a mother, and a thing called a daughter, and a thing called a cottage, and told yourself that if you put them all together you had a thing called a happy family.
