Lol spot on! It's hard to get to know people working on their career. It's one of the reasons why DC dating can be so lonely and noncommittal.

Best bets are with locals or others who aren't here just for work. There's a whole side to DC that isn't in the government-work orbit and they are some of the best people I've met in the country. Conscious of issues and government, but not absorbed in it, and more likely to put other things in life first.
