Is this a real question? You name a whole bunch of southern things and then you lose me by stating that people in NY have a problem with you holding doors and saying you’re sorry if you bump into someone. Are you holding the door when someone is still 50 feet away? My parents are from the Bronx and I am in Manhattan at least once a year and people say I am sorry when they bump into each other and hold the door for each other. Anyone who has spent any time in NYC gives directions with streets and cross streets, doesn’t matter where they are from. It’s one of the great things about being in a city that primarily uses street numbers places on a grid system.
