Exactly, pretty much. Given how confusing our language is, and how it's becoming more and more prominent about the world (although that's not exactly a good point, in my opinion), others are having to adapt to our words and try to fit them into their own languages. And since our language, as all do, is constantly evolving, we're never going to have a pure 'set' that everyone is going to have. We have stereotypes within our own language after all: inner-city, valley girl, l33t...but getting onto the point in movies that are set in previous eras, it does strike me as funny that the main characters may be in Renaissance France, and while every one of the main characters is speaking English (and often with British accents), the minor characters around them may be speaking all manner of different languages. Why should it be so different for them? I dunno. It was an excellent point that was made, however.
