One day, Gandhi was boarding a train. Unfortunately, one of his shoes slipped off his foot and landed by the train track. The train began to move away before he was able to retrieve the shoe.
So, he casually removed his other shoe and, leaning out the door, threw it back down the track near the first shoe.
Another passenger asked why in the world he would do such a thing. Gandhi replied that some poor man would find the first shoe which would be worthless by itself. But, now the man will have a pair of shoes he can use.
