But why would anyone on a joyous occasion rake over past unpleasantness and dwell on painful events horrible to experience and repellent to recall? Silence is mightier than words. It clothes the wreckage that befalls us in the deep folds of forgetfulness unless someone stirs up the painful memories for the sole purpose of edifying us by example and, as with illnesses, of helping us avoid the causes that led us to them.
Gregory of Nazianzus
