Oh, my god i'm beginning to wonder if this is a thing.
I've dipped in and out of this thread since posting, but my partner does exactly the same thing.
Knows, I have slight hearing loss in one of my ears as well.
He is the only person in my world where I am constantly saying what - pardon - sorry to. Because he mumbles mutters, or he presents the back of his head to me whilst he's talking. I don't know why he does it. We were sitting buy the river over the weekend, and it was quite loud with people having drinks outside and he decided to turn his head away from me and put his hand up to the side of his face which is muffling his voice.
He gets annoyed if I can't hear him.
Sick of telling him look at me when you're talking to me. He thinks i'm rude for saying what and he tuts at me and rolls his eyes, but he doesn't think it's rude for him to present the back of his head to me when he's talking to me a lot of the time.
A lot of times the time I pretend i've heard him or just ignore him or just start making stuff up.
It's absolutely infuriating, and I don't have this problem with anyone else.
