Additional context:
Native speakers of my mother tongue do not all understand each other due to some pretty extreme dialects. Now that I’m in Europe, I’ve noticed multiple instances of people sometimes not understand the dialect of someone from a village 10-20 km away…
In contrast, for example most American, British, and Australian people can just… understand each other like that?? I never thought much about it before but it’s pretty incredible
Edit: thanks everyone, and clearly I didn’t think of certain parts of the UK when I was in the shower and thought of this…
That’s… simply not true at all, not only is a common joke how native speakers from a typical remote area are easily unintelligible to geographically close cosmopolitan native speakers, but me, as a non native, have problems to understand most of the accents in English if I have not been exposed enough to them (skill issue probably, but I found it quite common in European English speaking environments)
