My wife and I have found what is (I think) a good way to resolve many things like this. When we have a disagreement about something, we stop and ask each other whether this issue is important to each of us. If we both think it's not important, then we just agree not to talk about it anymore. That's the "agree to disagree" case. If it's important to one of us, then we just do that. I don't have to agree with her that it's important to do it her way. If I don't really care what happens when I'm done with a glass, I do the thing she wants. The hard part of this is letting go of "being right" and just doing the thing that's important to your partner even if you don't think it should be important. But you really can decide to do this. Only if it's important to both of us do we have to keep arguing about it or figure out a compromise. Those issues are luckily rare.
