I think you need to be a bit aware of how you're coming over, sometimes you see someone's eyes glazing over. If you can do that you stand a good chance of doing something about it
I'm afraid that my now deceased in-laws really were boring. Same stories over and over again for 40 years, FIL in particular. And talking at table mostly about people that we didn't know, or the same old stories about things husband had done as a child, no new ones, just the same ones that actually made them look bad. I honestly don't think that they knew what I did as a job, or hobbies, sister in law has said that too. Judging my family too on very little evidence, and they weren't interested in hearing anything about them, so I think they just zoomed in on things that fitted their narrative. I remember fil ringing to tell me all about their recent holiday, which included lots of incredibly boring details about the minutia of their journey - where they stopped on the motorway, and suchlike. No way of getting a word in sideways to ask about what they found interesting in the town they visited, I'm afraid I put the phone down for a few minutes, I did have a baby at the time, he was still going strong when I could pick the receiver up again.
I don't mind hearing about things that people find interesting and tell me about the interesting things, and allow a breath for me to maybe ask a bit about it. But when he did that at our silver wedding celebration, on that occasion he went on about how much better the food had been in that country and how much better the waiting staff were [in the earshot of our waitress] , on and on, even going on about it afterwards to our son, we went for a little walk afterwards, and I could hear him across the field, about how the foreign waiting staff were so much better
Well, our local ones seemed file to be honest, not sure what his problem was. That was both boring and shockingly bad manners
He actually went down with dementia, but it wasn't much differentto be honest
