Peggy the milkmaid was going to market. There she planned to sell the fresh, sweet milk in the pail that she had learned to carry balanced on her head. As she went along, she began thinking about what she would do with the money she would get for the milk. "I'll buy the plumpest chickens from Farmer Brown" she said, "And they will lay eggs each morning. When those eggs hatch, I'll have more chickens. Then I'll sell some of the chickens and some of the eggs, and that will get me enough money to buy the blue dress I've wanted and some blue ribbon to match. Oh, I'll look so lovely that all the girls will be jealous. But I don't care; I'll just toss my head at them, like this!" She tossed back her head. The pail flew off, and the milk spilled all over the road. So Peggy had to return home and tell her mother what had happened. "Ah, my child," said her mother. "Don't count your chickens before they're hatched.""... and they will lay eggs each morning."
