US to Switzerland
-Culture shock, go an hour or less in either direction and have people speak completely different languages with little experience with the other.
-Don’t make noise after 10pm. Seriously, don’t do it. I got noise complaints for “flushing the toilet too loud”.
-People are touchy and also extremely reserved at the same time. Meet someone for the first time or see a friend? Kiss on the cheeks three times. Accidentally touch someone on the bus? Shame on you.
