Drew Brees sports a "Bitter Smile" just after the New Orleans Saints' loss to the Baltimore Ravens on December 19, 2010. Unbelievably, the vast majority of people believe they are truly smiling when they wear this facial expression. Here, we know it's context - so it's easy to be the Monday morning quarterback. But this facial expression is often seen in other contexts where its meaning is not so "black and white". It is commonly seen in business and in social settings and its meaning and ramifications are almost always unobserved, misinterpreted or dismissed.
