They're/You're doing it again!
Damn snobby Frenchmen so proud of your freaking French language :steam:
LOL (I'm kidding of course)
I have more anecdotal stories but I'll save them.
As for the 'cultural differences' = allegations of rudenes...I could see that. As an Asian-American with an immigrant background, when I travelled to Spain and then later Peru and Mexico, I saw lots of European tourists as well as interacted with "the natives".
I realized that American culture is actually pretty friendly and accomodating compared to 'pan European' culture (though my friend who visited her brother somewhere in Scandinavia said people were pretty friendly and approachable).
In really crude typology generalization terms, there is a good bit of Fe that is praised in American culture. Of course there are many people who are NOT friendly or helpful, but these traits are praised and prioritized in the US. - think about the all-American cheerleaders and the idea of being a "good neighbor".
That kind of Fe and *going out of your way* to help people or SHOW people you are happy and like them etc. - not so much for Europe. (BTW, have you ever watched British TV to see their "American" characters? It's hilarious to see how they view Americans)
This is a WIDE generalization, I know, but just go to Madrid if you're wondering what I'm talking about. Or just ride on Iberia Air (I made so many jokes about Franco when retelling my Iberia Air nightmare stories) Har har har. It's just a very different culture with a different baseline for accepted/acceptable behavior (this would be Northern Spain/Southern Mediterranean Andalucian Spain has a very different vibe). I found people in Mexico City to be very nice/friendly/helpful but I think it was also the closeness to and familiarity of the US but overall it was by far the friendliest city for 'outsiders' that I had visited (even in relatively larger cities in Spain like Sevilla I encountered some straight up ignorance). And I would say folks along the Mediterranean, whether in Spain or France would probably be warmer (more Fe) and laid back than their northern counterparts.
Also, tourists from the 'developed world' can be assholes when visiting 'developing countries' so maybe that partially skewed my view.
But yeah, travelling to these places did make me recognize *expectations* and priorities in a culture - namely that for all the (valid) criticism Americans can get for being rude and boorish at least at a baseline level being "friendly and neighborly" are actual basic American values ... at least theoretically.
