Because of fear of reprimand, he ran out of the house. He went up to the valley and shouted, “I hate you, I hate you,” and back came the echo, “I hate you, I hate you.”
This was the first time in his life he had heard an echo.
He got scared, went to his mother for protection and said there was a bad boy in the valley who shouted “I hate you, I hate you.”
The mother understood and she asked her son to go back and shout, “I love you, I love you.”
The little boy went and shouted, “I love you, I love you,” and back came the echo.
That taught the little boy a lesson that our life is like an echo: We get back what we give. Benjamin Franklin said, “When you are good to others, you are best to yourself.”
