I lived in an outer borough of NYC a combined total of 10 years. All of my family except for one sister and her family still lives in NYC and Long Island.
I think I am qualified to say that most people in NYC genuinely don't care about anyone else, if you are a poor homeless person panhandling on the streets, they will walk by you as if you don't exist. If you are a rich person wearing a 3 piece suit, coming out of a limo to go to Del Frisco's, and if you so happen to block the sidewalks, they will cuss you out. That is NYC, no one's gives a crap about anyone else.
