I hate to even write about this but I have to….
People here pick their nose a lot… In public… While standing directly in front of another person….
One guy on the subway, was aggressively going after some nose hairs and/or boogers for about 10 minutes.
Students (and not just my babies) do it through out class, even when they are having a direct conversation with you. Their finger will be jammed up their nose.
I’m not really sure what the reason is or if there even needs to be one but it is definitely an intriguing difference in cultures.
