Once there lived an old man who kept all different kinds of animals. But his grandson was particularly intrigued by two tigers that lived together in one cage.
The tigers had very different temperaments. One was calm and self-controlled while the other was unpredictable, aggressive, violent, vicious, and prone to despondency.
“Do they ever fight, Grandfather?” asked the young boy.
“Occasionally, yes they do”, admitted the old man.
“And which one wins?”
“Well, that depends on which one I feed the most.”
