"What is it that differentiates human beings most revealingly? Some say it is their varying degrees of compassion; others say it is amounts of prudence; still others, people's differing appreciations of beauty, or whatever makes them angry. And there are other possibilities worth considering. But in truth nothing is so revealing as a person's sense of humor."
It is not very hard to notice the many differences between people. There are thousands of things that differentiate us. Appearance is of course the most obvious but in reality appearance does little to actually distinguish people outside of identifying them. Having blue eyes does not say anything about my attitude, my beliefs, my likes or dislikes. Of course there is no one, single character trait that will best identify a person. Humans are extremely complex. Most of us spend our entire lives trying to figure one another out. (This is especially true when attempting to figure out females.) Clues can be found anywhere. The books a person reads, the movies they watch and the games they play all reveal little bits of their character.
It is a fair comment though that the most revealing character trait a person has is their sense of humor. Few things are as distinguishable and noticeable as humor. Laughs echo throughout rooms and they are as unique as snowflakes. Jokes have been told and retold for centuries by men and women of all races. While it has often been said of someone that "they have no sense of humor," it is untrue. Senses of humor vary more often than the weather. What some people find hilarious, others find offensive. What some people think is stupid, others think it is amusing. This is why it is so revealing. What makes people laugh or smile can say a lot about their intelligence, their convictions and their social standing. Of course these are just a few of the facets of human life that a sense of humor can reveal.
