Yeah me too. Visited China last year to see some old friends. It was surreal how my own mindset towards the country had changed in a span of a mere 5 years or so. Instead of putting on a constantly smiling, buddha face I would just look taut the whole way. Thought about buying an mini foot massage machine and using it on my face to loosen the muscles...lol; Just didn't bother working up any emotions when a group of girls walked by, nor did I try and nod towards groups of boy as if to show camaraderie. Acted like anyone else in New York City walking down Times Square at 9:00 in the morning. It's surprising how long the simple things like acting as your would back home can take to settle in.
