Why are people so rude in SF? There is a level of passive aggression that is seething below the surface at all times. Try waiting in a car at a stop sign. Watch pedestrians step out without pausing or even glancing in your direction. See them amble as slowly as if they were meditating alone in a mountain meadow, To acknowledge your presence in any manner, let alone to make eye contact or show that they have seen you at all, is regarded as an intrusion on their "rights." In London pedestrians usually speed up their pace a little in recognition of the waiting vehicle. Here, while one person is making his slow way across the street, many more will pour into the intersection without looking at the waiting driver or offering even a nod for his or her patience. God help you if you drive through the intersection after the pedestrian has stepped past your path but not fully reached the opposite sidewalk … the looks, the gesticulations, the profanity! Why has anonymity been replaced with actual hostility? Why is courtesy so quickly set aside in favor of entitlement? Would you behave like this if this were your home town whee you might be recognized by your parent, teacher, dentist or neighbor?
