'You can pick my apples and sell them. Then you will have money.' The boy was so excited. He picked all the apples on the tree and left happily. A few years later, the boy returned. He told the tree that he wanted to go sailing around the world.'Use my branches (树干) to build your boat. You can sail far and be happy.' So the boy cut the tree branch to make a boat. He went sailing and didn't return for a long, long time. Many years later, the boy returned. 'Sorry, but I don't have anything for you anymore,' the tree said, crying. 'All I need is a place to rest. I am tired after my travels.' The tree replied: 'Good! Old tree roots are the best place to rest.' The boy sat down and the tree was glad. The tree in this story is like your parents.
