George Carlin once said, “Everybody smiles in the same language.”
In fact, our facial expressions can convey a plethora of information about our emotional state. Take, for instance, a scenario in which you see a loved one frowning, choked up, and on the verge of tears. Your response is to throw open your arms and wrap them in a hug. Without saying a word, you have had, in fact, a conversation, in which your loved one has conveyed sadness and you, the want to comfort and perhaps understand why they are upset.
