Did you ever read the story of Goldilocks to your children? In one version of this story, Goldilocks is a tired, hungry, and lost little girl who encounters a house owned by 3 bears. She finds 3 bowls of porridge and judges whether each is too hot, too cold, or just right. She then finds 3 chairs, and determines whether each is too big, too small, or just right. Finally she is tired and finds 3 beds, and she assesses whether each bed is too hard, too soft, or just right. After she eats the porridge, sits in the chair, and lies on the bed that are all “just right,” she falls asleep.
