Anyone who understands humour well will accept that it is a damn serious business. Again, if well understood, you should be able to laugh at yourself. Living life (as opposed to surviving) is better experienced with humour. A person without a sense of humor is like a wagon without springs, jolted by every pebble in the road.
How is comedy associated with life? What is the relation? In Charlie Chaplin’s words, Life is a tragedy when seen in close-up, but a comedy in long-shot. Horace Walpole adds: Life is a tragedy for those who feel, but a comedy to those who think. Humor is emotional chaos remembered in tranquility.
I always used to think that ‘people should have sense of humour’. Actually, it turns out to be the other way: Sense of humour should accept us. In lighter terms, if you can look into the mirror without laughter, you have no sense of humor.
To sum up, common sense and a sense of humor are the same thing, moving at different speeds. A sense of humor is just common sense, dancing!
