And anyway, in Prague, they always try to explain me something in English first
It is off topic here, but Prague is hardly a typical place in Czechia.
In Brno it's rare to find someone that speaks English lol
In response to the previous comments, in fact many young people in Czechia all over the country speak very good English, far superior to my Czech! We've been a bit embarrassed about this -one reason my wife and I are doing this course.
