A New Yorker never waits on line for a cupcake.
Walking slow on the sidewalk is always a clue that someone is from out of town. Looking up at buildings while walking is another one; New Yorker’s know what’s up there, we don’t have to look.
Real New Yorkers do not turn around when someone starts a loud, lunatic rant on the subway; we ignore them. We also do not turn around when someone starts a fight on the street; we quickly and anonymously walk away, because you never know who’s carrying what weapon on them.
Real New Yorkers have more than one lock on their doors. Also, you can always tell a native college dormer apart from an out-of-towner, because the New Yorker will always lock their door, while the non-native will simply walk into the hall without thinking about it.
