Once a king asked an artist to paint a picture by him. He told the artist he didn't want to
any shadows in picture, just sunshine. When the king saw the finish picture, he was
disappointed. Without shadows, everything in the picture looked flat or unreal. The point of the
story was that we need both shadows and sunshine to have a completely picture, just as we
need both rain and sun to have a living world. People, too, needs both sadness and happiness.
We often learn important lesson during sad times. So when we feel sad, we should try to think
about that we might learn from the experience.
