It’s very noticeable in Moscow that people who are strangers or barely acquainted don’t really greet each other. For example, during a jog in the USA or Europe, it’s quite rare that a fellow jogger won’t throw you a casual hello. And there’s no need to even mention the neighbors. In Moscow, it’s quite the opposite: it’s rare for someone to greet you. Also, there’s a suspicion that if you do something wrong, here they prefer to make remarks over asking you not to do something. I never really noticed it before.
