"We are drinking and you are paying."
Translation:Wir trinken, und du bezahlst.
Hey, I was questioning myself with that one too, but in Deutsch Exchange they have a cool explanation for it: https://german.stackexchange.com/questions/7097/when-to-use-bezahlen-and-when-zahlen
This conversation in English could easily be one couple telling another couple that THEY are paying, which could easily mean using plural "you".... apparently "Wir trinken und ihr bezahlen" is wrong.... WHY do we have such an issue with plural you and singular you in English? Normally Duo accepts, plural and singular . Why not now seeing as this is ambiguous?
