A ferry boat was once crossing a river. Suddenly the boat struck a rock and
water relentlessly poured into the cabin. The passengers were frightened out of
their wits. Only one man sat calmly as if nothing had happened and even laughed
at the way the others were so alarmed.
"Don't worry! It's not our problem," the man said. "It doesn't
matter if it's leaking because it's not our boat."
