My ex and I used to have fights about something very close, but not exactly this. Instead of asking, say, "Will you wash the dishes, please?" she would instead ask, "Do you want to wash the dishes?" She'd get extremely annoyed with me when my answer was, "No, I don't want to, but I will." Apparently, the idea that it needed to be done and that at that particular moment it would be easier for me than for her were enough that I was supposed to *want* to do it, even though it was something I didn't like doing and found a rather unpleasant task. It wasn't enough that I would do it, I had to want to do it.
