Once there lived a blind man in a small town. He always carried a lighted lamp in his hand whenever he went out at night.
On one dark night he was going with his lighted lamp in his hand. A group of men were passing that way.
They saw the blind man and made fun of him. They said," O Blind man why do you carry the lighted lamp. You are blind and cannot see anything?
The blind man politely said, "This lamp is not for me, but for you people who have eyes. You may not see a blind man coming and push him. They felt ashamed and begged pardon.
Think twice before you speak.
