Laughter Laughter is surely one of humanity's greatest gifts, for the ability to laugh--- to appreciate the pleasure or absurdity in daily activities---- allows people, young and old alike, to keep problems in perspective. Children are natural laughers. In situations, both appropriate and inappropriate , the chuckles,giggles,and outright peals of laughter of children can emphasize their innocence,their joyful ignoranceof the problems of the world. Levityamong adults is, unfortunately, far less common, but it is equally welcome. How fortunate are the adults who can react to potentially frustrating.situations--- a collapsed tent, a split seam in a pair of pants, a surprise guest--- and see the sheer.absurdity(荒谬) of their attempts to maintain absolute control. Laughter expresses pleasure, eases(缓和) tension, and lifts the spirit,. It is a gift we should all share more often.
