Once upon a time there lived a poor farmer called Smith. He didn't like to share things with others. Smith had a friend who was famous for the wonderful apples he grew.

One day, his friend gave Smith a young apple tree and told him to take it home and planted. The farmer was pleased with the gift, but when he got home, he did not know where to plant

He thought and thought. Finally at night he planted the tree in his wood where no one could see it. But without sunlight and good soil, 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. "If I had planted it near the road, strangers would have stolen the fruit. If I had planted it in one of my fields, my neighbors would have come at night and stolen some of the apples. If I had planted it near my house, my own children would have taken the fruit,"

"Yes," said the friend, "but at least someone could have enjoyed the fruit. Now you not only have got nothing, but also you have destroyed a good apple tree."
