It's a feeling we might have more often than we'd like to admit, some of us anyway. I will never fit in to DC. No way. Not going to happen. Might as well admit it. You just started seeing things pretty much the opposite way from the norm, and it seems you can't really go back.
You go back only when you've really acknowledged all that, which takes a good sense of humor, touched with forms of surrender to the facts. No sense in trying to impress anyone. Just like you're from a different planet.
