One day a visitor from the city came to a small rural area to drive around the country roads，see how the farms looked，and farmers earned their living. The city man saw a farmer in his yard， holding a pig up in his hands，and lifting it so that the pig could eat apples from an apple tree. The city man said to the farmer，I see that your pig likes apples，but isnt that quite a waste of time？ The farmer replied，"Whats time to a pig？"
