It is truly crazy how often it comes up. Moreso than the weather. Particularly in Europe.
It really shouldn't be a surprise:
- USA is a super power in terms of economic, military and cultural might
- English is pervasive
- Our politics are a show/sport and the rules are unique
- USA/Europe current events: Ukraine/Russia war, USA alignment towards Russia, tariffs, ascendant right wing populism, immigration backlash, co-Pres Musk
- Trump is unique in terms of personality, character and conduct: Absurd statements, criminal cases, cult following, 1/6 insurrection, merchandising
And on and on.
Of course people will be curious, fascinated, disgusted, delighted, all sorts and are sometimes curious in hearing what it's really like from a native.
