I saw a version of Hansel and Gretel in which the old woman invites Hansel and Gretel into her candy house and after asking them, "what would you like to eat first-some candy? some cake? Hmmm?" by the light of her lantern the old lady cast a frightening shadow on the wall, then the children scream and the old lady asks, "Is something wrong?" then the old lady turns into a witch, the candy turns into wood, the cake turns into a cage, and the candy house turns into a tree stump house. Do you think the old lady turned into a witch, the candy into wood, the cake into a cage, and the house into a tree stump house by accident or on purpose and why?
