Some guy will post a picture of a pretty standard looking pepperoni pizza and say: "Imagine not living in new york." And then there's the whole bodega discourse, which is also funny. "For you non-new yorkers, let me explain: a bodega is not a corner store. It's a place where you can buy gatorade, toilet paper, AND eggs." Thank you sir for explaining that to a slack-jawed yokel such as myself.
Gonna be honest NYC is not going away, it's just changing. It's changed several times over the decades. Your NYC is probably going away though, sadly. NYC of the 1940s is totally different from the NYC of the 1970s is totally different from the NYC of the 90s is totally different from the NYC of today.
