It occured to me, while watching drivers and pedestrians random travel on the streets and sidewalks around me, that one big reason for rules and laws is so we can predict what other people will do. This may explain why “different” = “bad” for so many people; “different” = “unpredictable”. It would also explain culture shock, where people persist in doing things that your experience tells you they shouldn’t. Sort of like cultural jet lag. You’re never too old for banal insights!
