Today I read a story. Its very interesting:

Voltaire had a servant, but he was lazy. One day voltaire said to his servant:Assef, fetch me my shoes. When Assef ought the shoes, Voltaire saw them covered with mud.

He asked:Why dont you wipe them?

The servant answered: No Sir. The road is muddy and in two hours your shoes will be as dirty as they are now.

Voltaire went out with a smile on his face.

The servant came running: But the keys? I need the key to the cupboard, and Ill have lunch.

Voltaire smiled:Oh!My friend, what is your lunch? In two hours you will be as hungry as you are now.

Voltaire is making use of the power of humor to make human relations warm and harmonious ,and have a more pleasant life.

I think I should also learn voltaires humor, so as to deal with things better. And humor makes people attractive.
