A comment I wrote on a post by Sarahjane, an American in Frankfurt, about vulgar young Americans abroad:
Right after I first moved to Berlin in 1991, I became extremely aware of the American junior-year-abroad students traveling on their rail passes. Even when they were not vulgar (and they weren't vulgar that often, at least back then), I noticed how they always seemed to believe that they were where they belonged, no matter where they were. Or to put it another way, that they had a right to be wherever they were, and to behave in the same way that they would have behaved if they had been in New York City or Minneapolis or Oberlin or wherever. The young Americans traveling together did not seem to have much respect for the countries they were traveling through; it was almost as if those places did not exist as separate cultures, but just as place for Americans to travel through.
