It's so amazing how people can be so lonely in the U.S. You can be living in a neighborhood without seeing the neighbors at all. Your closest friend or family could be several miles away.
It's also amazing how automated things are: ATM bank machines, highway toll stations without cashier, gas stations without pumpist, or a car wash station without car washers.
Some people go out so underdressed! Guys wearing sandals and shorts to go to work, eating and drinking while waiting for a bus or while walking along the sidewalks.
