I drive for a car service. The clientele is half business, half leisure. They are similar in that every one is on the cell phone to family or close friend. They're in the back having a conversation in the dark with someone who isn't there like talking to a neighbor over the fence at night. I turn the rear view mirror up so we don't have direct eye contact and keep the radio on low volume. I become a part of the landscape like a streetlight that seems to see and hear everything but is perfectly discretionary.
