I am not sure what you mean by "culture shock". I experienced culture shock when I went to Moscow in 1999, but I expected that, since I was traveling to another country that was very different from the USA, where I live. Are you saying that returning to Moscow in 2012, 13 years later, would be a different kind of culture shock? I'm a little confused. You seem to be saying that everything is so completely different from the way it was in 1999 that I will be shocked to see how it has changed. Is that true? Have things really changed that much?
