Azul, you've made very valid suggestions which I've already tried.
Just accepting what she's saying riles her, challenging unacceptable comments the same. Am in danger of repeating brother's comments last year, which could bring on a stroke or worse.
We've no appointments this week, so will see if she calls me. Also supposed to be going clothes shopping, but can't face it at the moment so went on my own. No doubt I'll confess to that at some point, lol!
