        A poor farmer had a friend who was famous for the wonderful apple tree he grew.

       One day, his friend gave the farmer a young apple tree and told him to plant it. The farmer was pleased with

the gift, but he did not know where to plant it.

       He was afraid that if he planted the tree near the road, strangers would steal the fruit. If he planted the tree

in one of his fields, his neighbors would come at night and steal some of the apples. If he planted the tree near

his house, his children would take the fruit. Finally he planted the tree in his wood. But without sunlight and good

soil (土壤), the tree soon died.

       Later the friend asked the farmer why he had planted the tree in such a poor place. "What's the difference?"

the farmer said angrily and then told what he had thought.

       "Yes," said the friend, "but at least someone could have enjoyed the fruit. Now you not only have robbed

everyone of the fruit, but also you have destroyed (毁掉) a good apple tree!"
