When I lived as a teenager in the U.S. it seemed to me that the people around me were modeling their behavior and way of expression on what they had seen on TV. Years later, as an occasional visitor, I think their behavior is just as conditioned by conventions. Perhaps social psychology or similar disciplines have developed ways of evaluating and describing this phenomenon more successfully.

For some reason, I feel like an outsider here more than in most other countries, even though, on the basis of my life history, language and culture, this is where I could be expected to feel most at home. Yet I have this feeling of having stepped into a dystopian movie like the Truman Show or The Invasion of the Body Snatchers. I'm really grateful that I don't have to live in this country - I would probably go crazy.
