My dad is like this with his hearing aids. He can basically hear nothing without them, but he’ll still try to talk to Us. So he gets them, but then says it’s too loud, so he turns it down to where he still can’t hear anything. One of them stopped working, and rather than call the doctor for a replacement, probably under warranty, he’s just like “oh that one stopped working”. So meanwhile, he’s basically impossible to communicate with, but doesn’t tell people “what did you say? I couldn’t hear you”, he just acts like he heard them and then just makes up whatever he thought they said.
