You live within 20 minutes of at least three different malls.

You don't think of fruit when people mention "The Oranges".
You know what a "jug handle" is.
You start planning for Memorial Day weekend in February.
You know that this is the only "New __" state that doesn't require "New" to identify it (like, try...Mexico,...York, .Hampshire - doesn't work, does it?)

You've NEVER, NEVER pumped your own gas.
You don't understand why there aren't more 24-hour diners elsewhere in the country.
You know where every "clip" shown in the Sopranos opening credits is.
