Lucky if I meet two a year and have lived here twenty four years. I understand there are more out there but not many. Happy that your friend is willing to make an effort to learn. Would you like me to make a video for YouTube proving my point? Foreigners who are fluent have asked the same their hunch less than 10% . My guess about 1% if that.
I don,t tend to go showing mine off in public. Hey look everybody I have a $$$$ for the week I think I might marry her. When I see foreigners showing off their rentals in public I can,t help but cringe.
