For me the killer is the “master of the universe” feeling you get in the United States coming from India. Everything is in order and under control from the lawns in suburban homes, to supermarkets and libraries to traffic and restaurants. You see a lot more straight lines and perfect Bézier curves. This is a completely different texture in extreme contrast to India where “chaos” reigns and the spices and smells are a lot sharper.
After coming back to India. I somehow feel more “free” and “alive” in the chaos. Giving up control feels like a more natural, intuitive way of living and dying.
