Here's how the story illustrates this theme:
* The "respectable" businessman: The story begins with a young man, the narrator, observing two passengers on a train. One is a well-dressed, seemingly successful businessman, while the other is a rough-looking man with calloused hands. The narrator initially assumes the well-dressed man is honest and trustworthy, and the rough man is a criminal.
* The "criminal's" true character: However, the story reveals that the "criminal" is actually a kind, compassionate man who is trying to help his sick wife. He is giving up his meager possessions to buy medicine for her, while the "respectable" businessman is a con artist who is trying to steal the man's money.
* Appearance vs. reality: The story shows that appearances can be deceiving, and that people's true character is revealed through their actions. The "respectable" businessman, despite his outward appearance, is actually the villain of the story, while the rough-looking man, who was initially judged negatively, turns out to be the hero.
In conclusion, "Hearts and Hands" teaches us that we should not be quick to judge people based on their outward appearance or social standing, but rather look for the true nature of their hearts and actions.
