Culture Shock on the Return?

We walked down the sidewalks of a busy American city. There were other people around, chattering away in English with absolutely no concern for how loud they were being. Nice, after 7 years of shushing the boys when they got too "loud" in European cities*. People were using the horns on their cars with (what felt to us like) abandon. Nice, after 7 years of living in a country where you only use your horn when you absolutely have to and can be fined for any use considered unnecessary. We could read every road sign, billboard, business name...all without having to mentally translate. Nice, after 7 years of, well...having to translate pretty much everything.
