A few of my Culture Shocks
-Not that I didn't know people here spoke Swedish, but it was a real shock sitting around with a bunch of Swedes & feeling usless ... not knowing even some basic words. Basically the shock was 2 year olds could communicate better than I.
-Food was a real shocker. Herring is a part of the lifestyle here ... Food for the Vikings. Watching people droll over smoked Eel, just nasty yuck!!!

I also married into a hunting family, who back then ... cleaned the meat at the kitchen table.
-washer/dryers. Closet dryers was a real challange for me, I had even iron our undies so that they would feel smooth

I now own a tumble "condense" dryer. Having patience for your load to finish a whole hour and a half.
more later.
