I find it very interesting that people using Bluetooth or an earpiece for their cell phones make facial expressions like they are talking face to face. I find it even more interesting, almost funny, when that person is angry. If they are happy, they usually smile with an occasional laugh, but anger is different. You get to see the eyes squint, the jaw stretch, and possibly the veins in the neck and forehead getting ready to explode! For me, it is such a guilty pleasure to watch someone lose their mind at an almost fictional character. Who are they so mad at? A husband? A client? A lover? A stockbroker? For me it’s fun to imagine the worst!
