Believe it or not, your mother probably believes she is empathising.
I tend to do what you’ve described (see, I’m doing it here!
) - maybe not *every time, but a lot, and TBH it took a random post I read recently (not on here) for me to realise that people don’t like it. I’ve done it all my life. The post in question suggested it’s typically an ADHD or autistic trait, either or both of which may be the (undiagnosed) explanation in my case. I have no idea whether this is the case with your DM, although tbh the screeching thing does sound a bit autistic, but I guess it could equally well just be lockdown loneliness or being out of the habit of talking to other people - as a PP suggested, not knowing what else to contribute to the conversation.
But I think I can shed light on what’s going on in her brain when she does it. It’s something like this.
You: I’ve got a bad back.
(Your DM’s brain: Right, the topic is bad backs. This is like one of those interview questions, ‘Tell us about a time when you experienced a bad back.’ I’ve never really had back trouble myself but I really want to show I understand.)
Your DM: Oh no, that’s awful. I know just how you feel because Moira at no. 25 had a bad back last year and she was in a terrible way for ages, I had to get her shopping for her.
(Your DM’s brain: Nailed it!)
She’s ‘relating’. She’s trying to show that she ‘gets it’ by recounting her own experience of it, even if that has to be at one remove. It was a literal REVELATION to me that this isn’t what people want! Possibly because if I was in the position of the bad-back-haver, and another person responded to me in the way that I’m guessing you want (and that I’m really, really working on!) - something along the lines of ‘Oh no, poor you, that’s awful. Are you in a lot of pain? Have you been to the doctor? What did they say? Is there anything I can do to help?’ - I would almost certainly find it weird and intrusive. Whereas if they made a few brief sympathetic noises and then told me about Moira, I’d be totally ok with that! I’d probably hope that they remembered enough to ask me how my back was next time we spoke, but that would be all the spontaneous empathy I’d be after. Unless I genuinely needed some kind of practical help, in which case I’d ask for it.
I think it’s just two very different ways of looking at the world and ‘empathising’, and I’m slightly horrified by people saying they avoid talking to their mothers because they do this!
