Devils advocate here, because this sounds like my wife and I. She gets really annoyed at me, but she doesn't understand that I don't expect her to answer my questions. I just need to let them out of my head so I can concentrate on the rest of the movie. What she could do is either just ignore me, or agree that it's a valid question and let it go. On some occasions, I may ask a question because I feel I may have missed something that she might have caught, but usually the questions are more rhetorical in nature...
