Sense of humor might be the most intimidating and scariest trait in someone. Think about all the fears we have about socializing, like rejection, humiliation, getting caught lying, isolation, proven wrong, etc. Think of what it would take for you to deliberately hurt someone through these methods. It’s not all that easy because that person can also defend/protect himself from such an assault. But when someone uses his sense of humor to get other people to laugh at you, there isn’t much you can do unless you yourself have the same talent to make fun of him. Sense of humor is not something you can study and work towards. It’s like being tall, you either have it or you don’t.
I think this is why so many women list “sense of humor” as a criteria in finding a man and not many men list it for women. It’s a modern version of physical strength to protect women. Humor is sexy for that reason. That’s my theory...
