One day, a hungry fox saw some tasty grapes hanging high on a vine.
He really wanted to eat them.
He jumped one - too low, He tried again-still couldn't reach.
He jumped many time's but the grapes were too high tired and upset, the fox gave up. As he walked away, he said, "those grapes are probably sour anyway. "
He said this just to feel better.
Lesson: it's easy to say something is bad when we can't get it.
