Once there was a small boy named chidi. He belongs to a poor family. One day, he was crossing through the forest carring some fire woods. He saw an old man who was very hungry. Chidi wanted to give him some food but didn't have food for his own. So he continued on his way.
On his way he saw a deer who was very thirsty. He wanted to give him some water but didn't have water for himself. So he went on his way.
Then he saw a man who wanted to make a camp but he didn't have woods. Chidi asked his problem and gave some woods to him. In return, he gave some food and water to him.
Now he went back to the old man and gave some food to him and gave some water to the deer. The old man and the deer were very happy. Then chidi happily went on his own.
However, one day chidi fell down the hill. He was in pain and couldn't move but no one was there to help him. But the old one who he had helped before saw him, he quickly came and pull him up the hill. He had many wounds on his legs.
The deer whom chidi gave water saw his wounds quickly ran into the forest and brought some herbs. After a while his wounds were covered. All were happy that they were able to help each other.
If you he others, then one day they will also help you.
