There's an attitude displayed by big-city people that must have a name in pop psychology. I'm talking about the world view that puts one's big city of residence at the center of the world. When I lived near Detroit, MI, everyplace not in Detroit or the suburbs was called "the outstate area" on the local news. So places in MI were in two categories: Detroit, and Not Detroit. Friends who live in or near New York City just call it "The City" as in "Hey, why don't you come in to The City and we'll have brunch." I just read an article on the New York Times website that called all states in between California and New York "flyover states" as in the states you fly over when you're traveling between the states that matter.
The way this attitude manifests here in DC is calling our city simply "The District." Like all the other districts are not The District, we are. This is made even funnier when you talk to people who work at the World Bank, housed here in DC. (Notice me skipping the whole discussion of the pretentiousness of the name "World Bank.") These people call their workplace "The Bank." All the other banks are not "The Bank," the World Bank is.
So you see in the wild these earnest 20-somethings dressed all in black sucking down $15 martinis tossing about phrases like "oh yah, I live in The District and work at The Bank."
