The strangest, saddest and funniest moments from around the world

Sadness is not usually valued in our current culture. Self-help books promote the benefits of positive thinking, positive attitude, and positive behaviors, labeling sadness as a “problem emotion” that needs to be kept at bay or eliminated.
