I have enjoyed our exchanges here.
I'm totally guilty (as has been pointed out to me by my spouse, frequently) of giving one example and then making blanket statements based on that.
If there's one thing I'm learning from my mother, who has dementia, and cannot be "reasoned" into thinking anything--is that sometimes you just have to say "I know," be kind, and then they are more likely to comply. That is vastly oversimplified, but I think we have to accept that some beliefs are bedrock--and the question becomes more, can we somehow make things marginally more acceptable, even without changing each others' minds?
Do you write here too? I would like to listen better to you as well.
