Very long ago, there lived a huge apple tree offering tasty apples to the people. A little boy became close friend to the apple tree. The boy used to play with the tree, climb the branches, sleep under the shadow, pluck apples, etc. Every day he visited the tree, and ate apples. The apple tree was so kind to the boy and enjoyed spending time with the little boy.   The boy joined school and could not spend any time with the apple tree. After several months the boy came to the apple tree. The tree was so happy to see the boy and asked him to play with it.   The boy said that he was not a little one to play with the trees.

Once a father and son went to the kite flying festival. The young son became very happy seeing the sky filled with colorful kites. He too asked his father to get him a kite and a thread with a roller so he can fly a kite too. So, the father went to the shop at the park where the festival was being held. He purchased kites and a roll of thread for his son. His son started to fly a kite.  Soon, his kite reached high up in the sky.  After a while, the son said, “Father, It seems that the thread is holding up a kite from flying higher, If we break it, It will be free and will go flying even higher.  Can we break it?”   So, the father cut the thread from a roller.  The kite started to go a little higher.  That made a son very happy. But then, slowly, the kite started to come down. And, soon it fell down on the terrace of the unknown building. The young son was surprised to see this. He had cut the kite loose of its thread so it can fly high...
