Once there was a tree and she loved little boy. And every day the boy would come and he would gather her leaves And make them into crowns and play king of the forest. He would climb up her trunk and swing from her branches and eat apples. And they would play hide and go seek. And, when he was tired, he would sleep in her shade. And the boy loved the tree very much. And the tree was happy.
But time went by, And the boy grew older. And the tree was often alone. Then one day the boy came to the tree and the tree said:
"Come, Boy, come and climb up my trunk and swing from my branches and eat apples and play in my shade and be "happy".
"I am too big to climb and play" said the boy. "I want to buy thing and have fun. I want some money. Can you give me some money?"
"I'm sorry" said the tree, "but I have no money. I have only leaves and apples. Take my apples, Boy, and sell them in city. Then you will have money and you'll be happy"
And so the boy climb up the tree and gathered her apples and carried them away.
And the tree was happy...
But the boy stayed away for a long time and the tree was sad.
And then one day the boy came back and the tree shook with joy, and she said:
"Come, Boy come and climb up my trunk and swing from my branches and eat apples and play in my shade and be "happy"."
Although it seems as if the boy is using the tree, the tree is content with being of any minute use to the boy, for the boys happiness is cause of her own.
