Been spending a lot of time on here!
My wife and I both grew up in Southern California and English for both of us is our mother tongue. But I still don’t understand her. 

When I was living in Istanbul, I went to see Acid House which depicted several loosely-connected vignettes set in Glasgow. I did eventually get the rhythm, but it took me half the movie to do so. In the meantime, I had to read the Turkish subtitles in order to follow the English-language dialogue

Edit: Forgive me, I misremembered. They were apparently set in Edinburgh.
