Once upon a time, a hungry fox walked down the riverbank. He gazed at the light-blue water of the river and, suddenly, he saw a shiny object afloat. First, he thought that it might be a tasty fish, so he jumped in the river and he tried to pick it up with his claws. But after more trying, he found out that he couldn't take it with his claws, because it was just the reflection of the bright sun above.
Afterward, he was more often hungry, because whenever he found a fish in the water, he thought that it's just a useless reflection. So he stayed hungry and hungry.
We must NOT learn from the first bad experience and we must always turn the other cheeks. That's what helps us to be developed.
