If you have ever seriously practiced drawing facial expressions, you might realize how odd the task is. It’s kind of startling to realize that as you make these lines to put a face together, you can recognize if that face you just drew is expressing fear, happiness, giddiness, facetiousness, worry, grief, shock, tiredness, anger, etc. You begin to realize that you had talents you were never aware of - the ability to glance at a stranger’s face and, in an instant, know what they are feeling. It’s an odd thought, but almost all people make the same sort of facial expression for the same emotions. Your best friend and the man sitting next to you on the bus will make the same face when they are surprised. You and a person who will be born after you have passed will have both made the same face when happy. It is one of the most ubiquitous yet unacknowledged skills we may have, and I think few people realize on their own how odd it is.
