Once there was a boy, who lived with his mother and father.
He studies well. He obeys his parents. He always stands first in his grade.
Day by day, her son falls into bad company. Under the influence of his friends, he got into some bad habits. He started disobeying his parents. He does not study well. He wastes time watching television. And when the results of the examination were out he got bad grades and failed in one or two subjects.
His father becomes worried for his son. He decided to teach his son a good lesson.
One day, his father brought a box of mangoes. In that box, every mango was fresh but there was also a rotten mango in it.
Father called his son and gave him a box of mangoes. He then told him to put all the fresh mangoes with the single rotten mango. The son does the same and puts in all the mangoes.
After a few days, the father told his son to bring those mangoes which he kept. The son brought those and saw that all the fresh mangoes got rotten by an individual rotten mango.
He asked his father, what was the reason behind this.
The father consciously told him that rotten mango spoiled all t
hat mango. Just like this one boy spoils another one.
The child realized his mistake in choosing a friend's company and thanked his father.
He immediately left the company and transformed into a good boy. He learned a good lesson now.
