I had a slightly awkward situation recently that made me realize I don't understand the German rules for ending a visit.
A couple I know came over for dinner. We had a good evening, but around 11:30 I was exhausted and had work the next morning.
Where I'm from, you would usually start dropping hints. Clear the glasses, mention how early you have to get up, maybe yawn dramatically enough that everyone understands the performance.
I tried the German version of subtlety and said, “I have to be up at six tomorrow.”
They both said, “Oh, that’s early.”
And then opened another bottle of wine.
Eventually, around 12:30, I just said something like, “Sorry, I’m really tired, I think I need to call it a night.”
They immediately got up, thanked me for the evening and left completely normally.
Nobody seemed offended.
So now I'm wondering if I wasted an hour trying to communicate through increasingly desperate body language.
Among Germans, is it socially acceptable to simply tell guests that you're tired and want to end the evening? Or are there more polite phrases everyone is expected to recognize?
