This incredible moment, captured in an image by Matt Munson this past weekend, has gone viral while elevating the national dialog regarding respect, aspects of parenthood and empathy. Almost no one would blame children of this age for climbing on many things which are "climbable" (and even some that are not) - yet at this instant this photo of two children climbing on the Vietnam Women's Memorial was taken ... their parents were laughing.
From a nonverbal perspective, the two gentleman expression's on the right act as mirrors for what most other people feel that see this image. We are immediately drawn to the National Mall with them.
The man pushing the wheelchair has primary expression of disgust - recognized most easily by his mid-facial tension and flaring of his nostrils.
Also of note are the temporary, deepened furrows which course from the sides of his mid-nose to the corners of the mouth (nasal-labial furrows). Both of his lips are elevated and the lower one is protruding. The chin is subtly dimpled and his torso is also leaning away. Notice that his eyebrows are both lowered (all of the above are consistent with disgust) but they're also drawn together - indicating the presence of a component of anger. At the same moment his forehead is also contracted and elevated - projecting disbelief. The simultaneous emotions of disgust, anger and disbelief are completely within the emotional context of this scenario.

A picture tells a thousand words ... and a few very powerful emotions.
