Mary was a milk-maid. Every day, she’d milk the cows and earn money by selling the milk. One fine afternoon, Mary was headed to the market carrying a pail of fresh milk on her head. On her way, she starts daydreaming.
She says to herself “I will buy eggs with the money I make from selling milk. The eggs will hatch into chickens which will grow into hens. Then I’ll sell the hens and with that money, buy a big house on the hill. When everyone in the village asks me about the secret of my wealth, I’ll refuse to tell and toss my head.” While saying so, Mary actually tosses her head and spills the milk on the ground.
