To all those who think having to repeat themselves is frustrating, how frustrating do you think it is for those of us with hearing loss? The answer? Very.
When I first started to loose my hearing, I also tried not to ask people to repeat themselves, because I was embarrassed and, as has been said, most of what was being said was not that important.
Then I realised, that this non important stuff i wasn't picking up on, was about the oil that greased the whee!s of social conduct. A throw away comment might be unimportant, or might give great insight into how the speaker is feeling.
Without hearing that comment, id neverknow.
I'm lucky in that my friends and family have at least tried to understand my disability. They know that to get my attention on them in a noisy environment, touching my arm or using my name helps. Once I'm looking at them I have a fair chance of being able to lip read what they are saying.
Hearing loss can lead to social isolation.
The only thing the op is being unreasonable about is not calling out her "friend" at the time. At that is very understandable
