Not us (honest!) but someone at work, she seriously thinks it might come to that
Between us we have suggested:
Take it in turns to have it at ‘your’ volume. He won’t do that because he “can’t hear it at all” at her level so no point watching
Get his hearing tested if he really can’t hear it at a reasonable level. No, he says there’s nothing wrong with his hearing
Have it halfway between the two. No because this is still too loud for her and too quiet for him so no one’s happy
Watch in different rooms. No because they didn’t get married to spend every evening apart (which is actually fair enough)
Any other suggestions I could put forward?
