Theory:

      Once upon a time there was a farmer. He lived in a village, up in the hills, beside a forest. In his farm where he grew many kinds of vegetables, he also had an apple tree. For many years the farmer and his family had enjoyed the tastiest apples from the tree. As a boy, the farmer and his friends played under the apple tree. They played hide and seek around the tree. They climbed the tree and swung on it and in season they plucked and ate the apples.
 
     As the years passed the boy grew into a man. He took over the farm and continued to enjoy the fruits from the tree. In the meantime many small animals and birds started living in the tree. The man’s children and their friends started playing under it. The large and shady apple tree now grew old and was bearing fewer and fewer fruits. It was nice to sit under its shade in the summer but nothing grew under it. The farmer felt the space could be used to grow some vegetables. He also felt he could use the wood to build a new room in his house. Therefore, he decided to cut the tree. He did not think about the wonderful times he and his friends had playing around the tree or the delicious apples they ate. Rather he felt the tree had outlived its usefulness and should be cut down.
Explanation:
  
Once there lived a farmer in a village. The village was in the hills, with a forest nearby. The farmer had a farm, where he produced many kinds of vegetables and fruits. One among such trees was the apple tree. The apple tree had been living since the farmer was a young boy. During his childhood, he and his family had enjoyed tasty apples from the tree. As a small boy, he had played hide and seek under the tree with his friends. They climbed and swung on the tree apart from plucking apples during the harvest season.

The farmer's family had enjoyed the tastiest apples from the tree!
  
The small boy grew up and became a farmer. He started farming in the land by himself. Not only did the farmer enjoy the fruits from the tree, but many small animals and birds also started living in it. Like how the farmer had played there in his childhood, his kids were playing around the tree now. The huge tree was getting older. It did not bear many fruits anymore. The shade under the tree was cool, and it was nice to sit there during summers. But fruits did not grow. The farmer felt that space could be occupied to grow some vegetables instead of wasting it for an old tree. He also made plans to use the wood from the tree to build another room in his house. He decided to cut the tree, but he did not think about the wonderful memories he had with the tree - how he had played around the tree with his friends and how they enjoyed the delicious apples. He only felt the tree had finished its time of usefulness, and it should be cut down now.
