I met this guy recently in my home town in India who was surprised to know that despite being in UK for the past 3 years I don’t listen to pop or western music. He was very much surprised to know that I am still a vegetarian. He was shocked to know that I don't smoke or drink even on formal occasions.
What is surprising to me is that, even in these days some people have this myth that you loose your qualities when you go abroad. When I asked my dad’s permission for my abroad trip his only condition was that I need to get married and take my wife along. Not that he didn’t have confidence in me; it was just the strong belief he had in foreign trips.
