Once a rich merchant was walking along the road with his servant. Out of the blue, a labourer carrying a heavy sack, passed by him. The merchant was hit by the sack and his hat fell in a nearby drain.
The servant thought that the labourer would now get a good scolding, but to his amusement, the merchant instead of scolding the labourer asked the servant to help the labourer pick his sack.
When the labourer went ahead, the servant asked the merchant for such behaviour.
The merchant said, "It was my mistake, not his. He was already carrying a heavy load. I should have walked carefully."
Hearing this, the servant praised his master.
The moral of the story is that a person should never blame others for his fault.
