Today I would like to share the following:
One day John paid a visit to the Ling's family in the country where he saw a pig with a wooden leg in the pigsty. He wondered and asked, "Ling, for what reasons does the pig has a wooden leg?"
"The pig is smart." Ling smiled.
"How smart actually?" asked John.
"My house caught fire before. It was the pig rescued my puppy from the fire." said Ling's father.

"I see. But, how come the pig has a wooden leg?" asked John.
"As it's such a lovely pig. I didn't have the heart to eat it up in one time."
What do you think of it? No matter how useful or how loyalty you are, you may get the same result .............
