I'm 28 and live in the Washington, DC area. The culture here is the same, go out, get as drunk as you can and stumble home and/or pass out/black out somewhere. Here it lasts well into your 30s. It's ended badly for me so many times, very badly, and don't want any part of it anymore. I plan to avoid a lot of outings for a while, at least until I feel stronger.
Hello, books, my new friends! Although I have managed to talk a few people over for a board game party. Carcassonne perhaps?
