She exuded abundant joie de vivre. Her joy was unconfined and unrestrained, it had no rhyme or reason, no grounds or motive, nothing had to happen to make her overflow with jollity. Of course, I sometimes saw her momentarily sad, weeping openly when she thought rightly or wrongly that someone had insulted her, or shamelessly sobbing in a sad film, or crying over a poignant page in a novel. But her sadness was always firmly enclosed within brackets of powerful joy, like hot spring water that no snow or ice could cool because its heat flowed straight from the core of the earth.
