Thanks for commenting, Beth and thanks for your perspective. My husband is also from New Jersey and many times people ask if he is British.
Most of the time the questions don’t bother me. To me, it’s the timing and the intent behind the questions that matter. And some people have terrible timing, reducing you to a stereotype. It seems they are standing there playing the guess-her-nationality-game while I am talking about something totally unrelated. So my message gets buried it seems.
You are right. It happens in every country and within every country. But it’s an interesting observation of human behavior.
