Whenever I get back from a long trip, my wife and I have this ritual. It sort of grounds me back home, lets me back in psychologically. Part of this ritual involves sitting on the steps of union square park in NYC and watching people going about their daily lives. Watching them shopping for clothes, for food, whatever – mostly watching their complete obliviousness to the hardships of another place thousands of miles away. Initially I get angry, but then I realize, that it’s all relative. That this is part of life, that most people are oblivious, because there is no other way to live. You can’t care about everyone everywhere.
