This is only tangentially related to the European vs. American personalities discussion, but I was listening to NPR on this morning’s commute and they were talking to a representative from the Estonian parliament about the letter signed by a number of countries trying to get the US House to bring the Ukraine bill up for a vote.
Anyway, he (the Estonian) did the full interview, then the journalist thanked him and he said, “You’re welcome, blah blah”. Then there was a pause like he’d just remembered something and he said “Have a nice day.”
I just cracked up. You know that some Estonian PR wag had briefed him for the interview and said something like “Be sure to tell him to have a nice day. It’s weird and I don’t know why, but with Americans you have to say that every time you talk to them!”
