It’s true everywhere, but you should keep some situational awareness of what’s going on around you. Try not to keep your head in your phone everywhere you go.

Also, you don’t have to greet everybody you see. In the city, that could be hundreds or even thousands of people just on your way to work. You show respect in a crowded environment like that by giving people their space and not engaging them unless it’s necessary or invited. Southern-style chitchat can easily be perceived as a time waster, or that you’re running a game.

On the other hand, there are exceptions to every rule, and that doesn’t mean you have to be mean like some sort of stereotypical New Yorker.

For better or for worse, people will ask what you do and talk about work in social settings. It’s also best to avoid politics and policy unless you also happen to be an expert. It’s likely whoever you’re speaking to already is.

PS- bring lots of money.
