There lived a black sheep in a nearby village. Every spring, he shaved his black wool and sold it to the villagers. The villagers made sweaters and socks from his black wool. 

One day, the black sheep noticed that he had some more wool left. He thought, ‘It would be such a waste if nobody wants to buy the wool.’ 

That afternoon, an old man came over to his wooden shed to see him. He wanted one bag full of the black sheep’s wool. Then an old woman came over. She also wanted a bag full of wool. A short while later, a little boy arrived. He also wanted one bag full of wool.

Therefore, the black sheep prepared three bags full of wool for them. He was happy that all of his wool was sold off. 

Moral of the story : 

We should be generous and helpful with what we have. We should be patient and not give up. 
我们对自己有的东西要慷慨大方，让其有所用途。同时我们应该耐心，不要放弃。
