Sadness is an emotion you can trust. It is stronger than all of the other emotions. It makes happiness look fickle and untrustworthy. It pervades, lasts longer, and replaces the good feelings with such an eloquent ease you don’t even feel the shift until you are suddenly wrapped in its chains. How hard we strive for happiness, and once we finally have the elusive feeling in our grasp, we hold it briefly, like water as it trickles through our fingers.
