Very familiar. i sure hope they don't call you to take care of them, if they get sick

in the metro areas, over all, people seem to be taking things seriously, but in the smaller towns in the less populous areas, it seems like business as usual, so far as packing the kids in the car and going to the grocery store.

Sorry, but "There's none so deaf as thems as won't listen.". (English proverb)

I think you've done all you reasonably can. I sympathize: my 82yr old mother is the same, and my trump card has been that I can't visit her if she goes out, but you don't have that incentive. My sister got even more frank than I was. She asked my mother to consider every trip and think, is this worth dying for? And dying alone, because we won't be able to visit you. It seems to have helped. I'm surprised your brother isn't discouraging them.

Let go. You can not protect them & they are not accepting of the facts so it is a lost cause. Like with addiction 'ya just can't fix it. They are making you the parent when they should be parenting you. But they are not. Your responsibility is to your children, not to your parents. They should be responsible as a parent to you.

My 85 y/o mom won't quit going to the store - even sends the home care people away who are paid to either take them or go to the store for them - because shes bored.

So if you figure it out, let me know, please.
