Answer:Life is a complicated twist of suffering, laughing, and learning all merging to tell a great story - or great many stories. Based on this view, "it is not the end goal or outcome of life that gives life meaning but rather the quality of the story, the quality with which one lives out and develops his or her role." At the time, this event seemed rather insignificant and did not merit remembrance. However, its catastrophic effects on my attitude that evening may have helped to mold me into the person I have become. I learned that suffering through such an event, as childish as it was, is quite necessary in any life. Such pains are part of an interminable cycle and only generate balance in one's life (p. 62, 'Life as Suffering'). Despite my horrid time spent that evening, the laughter brought since the incident is a worthy tradeoff. Laughter is an all too necessary function of life, just as suffering and the wide range of other emotions. "Some thinkers would emphasize the importance of sophistication in humor, but others would say that laughter itself is what is important." Whatever the case may be, laughter is an important ingredient in life, and must not be taken for granted nor ignored.
