COMPENSATION

...it was the great law of compensation--the great law that regulates Nature's heedless agents, and sees that when they make a mistake, they shall at the self-same moment prevent that mistake from working evil consequences. Behold, the same gust of wind that blows a lady's dress aside, and exposes her ankle, fills your eyes so full of sand that you can't see it. Marvellous are the works of Nature!
