Once a man asked a painter to painting a picture for him. He told the artist he didn’t want to any shadows in the picture, just sunshine, but the artist did so. When the man saw the finished picture, he was disappointing. Without shadows, everything in the picture looks flat and unreal.

The point of the story is that we need both shadows and sunshine to have a completely picture, just as we need both rain and sun to have 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 stop and think about that we might learn from the experience.
