It is certainly a crazy place. I don't get culture shock from it really - I've been visiting summers since I can remember, so things about it: the smell coming out of the airport, jasmine, honeysuckle, burning cow dung, incense - it's all incredibly familiar. But my cousin is certainly having an interesting time adjusting to America. Certainly, India has its own, very specific rhythms, but I haven't traveled that much in the rest of South Asia, so don't have much to compare it to on that front.
