The underlying belief that nobody likes grief is not a fact, I think. There are pessimists and sadists who see negativity and enjoy sadness. Commonsense says that people don't enjoy sadness, but the reality lies beneath the commonsense experience if "common-sense" is taken to be the "layman's sense." A person of emotions equally enjoys both the experiences, the experience of gladness and of sadness. Indian theory of taste (rasa siddhānta) recognises "karuṇa-rasa" (taste of tragedy) along with other rasas, also in all kinds of literature and cinema we have tragedy as we have comedy and others. The point, here, to take note of is that only those who are "persons of emotions" are considered common oft-times. But, there are commoners who have the least sense of emotions; they are to be regarded as commoners too for though they lack in usual sense of emotion nonetheless they possess commonsense intelligence.
