Kindness

 
A lady went to the headmaster of a boarding school, to recommend the son of one of her girlfriends.
I demand you to admit him in your institution; he’s rich!
The headmaster took a piece of paper and wrote a zero.
He’s beautiful!
Another zero.
He’s strong!
Another zero.
He’s skilful!
Another zero.
He’s kind!
After hearing these words, the headmaster put a one in front of the four zeros, and gave them their value. 10.000.
