In America, we don't have enough close neighboring countries that I have been in for enough time to get in trouble. I mean, I know a few Spanish cuss words, but I know when to not use them. And I accidentally used a Japanese cuss word with our exchange students that stayed with us years ago. My Dad didn't translate it as a cuss word when he used it after being part of the occupation force in Japan in WWII.
That is just too boring. However, America is bigger than most Europeans are used to one country being and we can have misunderstandings based upon the region of the country you are from. For example, in Kansas, the 3 meals of the day were breakfast, dinner and supper. In California, it is breakfast, lunch and dinner. That type of translation won't get you in much trouble.
But ... I did recall one that caused a real problem. My wife said we were doing something NEXT Saturday. So, Saturday showed up and ... I wasn't ready at all! I expected the trip to be a week off still. In Kansas, the coming Saturday is THIS Saturday and NEXT Saturday is the one following.
That's as good as I can do. I haven't had a topic I couldn't dig something out for in a coon's age.
