No offence intended. However, I find it odd that the Polish Duo team seems to put an effort into explicitly and deliberately countering known stereotypes.
none taken :). But knowing how to refuse is a good thing. (It's easier to say I can't drink, or I don't drink today, than saying no more after few shots.)
It is, but using the subject pronoun in a simple sentence like that one is rarely natural. That suggests "You drink? Pfff, WE never drink!". It puts more stress on the subject. But we always accept it.
