Ok ! I’m having a debate with the Lovely and adoring sister in-law ( Not) ….about replacing an item that you borrowed or used. Example: I finished a 1/4 bottle of Pinot Noir at my friends house while Cat sitting Ziggy ….so I replaced the wine and then proceeded to drink 3/4’s of that bottle so when he came home, everything was exactly the way he left it.
Before answering the question, ask your wife her answer and then share both. This should be fun
Of course my sister in-law felt that I committed a mortal sin.
If it’s someone you don’t know that well then you shoulda left them a new bottle of wine as a courtesy. Maybe even put a bow and a cute note on it thanking them. But since it sounds like you knew them AND you were doing them a favor, cat sitting, I’d say that last bit of wine was yours for the taking.
