One day, a school boy was on his way home and he was feeling thirsty but he had no money with him.
He branched at a canteen nearby and begged for water, the owner told his daughter to give him some water and the boy drank to his fill...
Many years later, the man was very sick and there was no money to treat him, his daughter took him to a private hospital around and plead that she will pay soon but they refused to admit the man..
Fortunately, a young man who happened to be the owner of the hospital appeared and told them to admit him..
To cut the story short, the young man was the thirsty school boy and that was how the kindness of the man saved him..
