Yes, the point is communication. In fact, it is pretty amazing we can all understand each others. Not just because of the language but also because of the different continents we live in and the diverse upbringings/cultures/ways.
I’m glad over here we don’t have dubbed movies. It allows us to hear different languages since we’re kids. Same with TV shows. When I was a kid there were a lot of French and Italian movies, both on the movie theatre and the TV. Now, as you know, it is mostly British or American ones.
My English friend, who lives up river, is trying to learn Portuguese. She manages to understand it a little, can read it fairly well, but she has some trouble getting understood. So far nothing close to your friend’s faux pas.
