Story of a milk maid
A milk maid was carrying a pail of milk on her head and was to market to sell it. As she went along she fell into day dreaming.
She thought that she would buy eggs with the money she got by selling milk After the eggs were hatched, she would have a large number of chickens.
They would fetch her high price. She would then buy fine silk dress for herself and look more beautiful. Princes would come to marry her, but she would toss her head and refuse them.
While thinking so, she did really toss her head in false pride. Down fell the pail on the ground. The whole milk was split and all her plans came to naught.
Count not your chickens before they are hatched.
