She has been asked of course she has, she is reluctant but by the same token does not want to be alone. The risk in this scenario is real and unnecessary. She is very vulnerable to C19. There us added pressure from another branch of the family who are putting it like if they don't want you, come here. It's ludicrous.
She is 94, it might be her last Xmas ? She might not even make Xmas ? Hopefully that's not the case but ....
I get your point and in the main totally agree but there is a balance to be struck when someone is that old ?
My old man is 81 and takes about 50 pills a day. Advised him not to go near Xmas day but not 100% sure he will take heed and ultimately who am I to judge him if he doesn't ?
