Hustysk Helens Adventskalender
Idiom: Mein lieber Herr Gesangsverein!
Literal translation: My dear Mr Choral Society!
Are you still keeping track of all our new friends? Luckily for you, they are all gathered for an after-work together today. Günther and Elvira, Sabine (who is not cross with Gudrun any longer) and Angelika, Rüdiger and Gudrun with her new boyfriend Alfonso. (Only Detlef is not invited and we all know why.) The friends are getting drinks at a Skybar with an excellent view. Angelika and Sabine have never met Alfonso before.

My dear Mister Choral Society is what you say instead of My Goodness, both for positive and negative statements.
Alfonso, a historian, is from Spain but moved to Germany and has learned German. When he starts speaking about “Dokumentationsmedien in der Archäologie” in German, Sabine’s eyes widen. “My dear Mr Choral Society!” she exclaims. “Your German is amazing!”
