For me it was not really a “false friend” situation but “begginer that can’t hear well” situation.
When I moved to Germany , after a week or 2, I was driving with a friend through the city and I saw the signal “Rathaus” and I asked my friend what was the meaning of that word ( because I was already thinking germans wouldn’t name a place “house of rats” hahahaha) .
Thing is, that my friend didn’t know how to explain it and the only thing that came to her mind was : That’s were Der Bürgermeister works.
I was amazed and my friend asked me if I knew Der Bürgermeister , to which I answer :
OF COURSE, I LOVE JÄGERMEISTER!
After 4 years, she keeps reminding me of that mistake…Specially when we drink…
Do you want some Bürgermeister, Stef ?
