I'm not going to call someone on it, but if you say you live in "DC" and you don't live in the District, then you don't live in DC. I don't care if its Tacoma Park, Rosslyn or any other perfectly fine place. If you live in Arlington, you don't live in DC. I'm not a native but this October it will be 19 years since I began living in the city. I mean, I've met people from Culpepper who say they live in DC.
