The first time my friend and I meet together, we have this uncanny ability to look at each other in the eyes and instantly recognize our respective facial expressions. Every time one of our mutual acquaintances says anything annoying or unusual, we both glance at each other, knowing that the third person has outraged or disturbed us as well, and we quickly exchange looks of understanding. The nonverbal emotions and communication of a stranger or an acquaintance, on the other hand, maybe difficult to comprehend and interpret in some situations.
