Rabelais: The most painful thing between people is to suffer annoyance and harm in a place where you think you deserve goodwill and friendship. Ying Lickak: Humor can be described as a kind consideration and artistic expression of life's incongruous parts... and the root of humor is the good side of human nature. Gorkya: Humor and seriousness are the test of each other, because if you are unwilling to accept a well-intentioned joke, there must be something suspicious in it, and a joke that cannot withstand scrutiny must also be wisdom.
