A young man ran a business in the market.
One day, he held up a shield and said proudly: “My shield is very strong.
It can stop any spear in the world.” Then he held up his spear and bragged: “My spear is very sharp. No matter how strong a shield is, my spear can pierce it.”
People all around here laughed when they heard the words of the young man.
One of them asked: “So, according to what you said, your spear is the sharpest. No matter how strong a shield is, your spear can pierce it. And your shield is also the strongest.
No matter how sharp a spear is, it can’t pierce your shield. Well, what will happen if I pierce your shield with your spear?"
The young man was too embarrassed to say anything.
