Gma, DNiece and her DBF have gone back. They were here ~ a week. We have a tiny house, so it was a tight fit. Yes, DNiece took good care of her Mom when they lived with Father-in-law(FIL). However, FIL had the sheriff's police come and kick them out, I suspect on a made up charge. They are always having drama, and some has involved calling the police, and once a few years ago, a court suit.
The "kids" will probably come back for another few days later, or maybe not...
As long as SIL is medicated appropriately, she is okay to deal with. She has some fatigue and health problems, but tries really hard not to be a bother, bless her heart. It was the GETTING her the appropriate treatment that was a problem!
Yes, anytime hands/wrists have problems, it's easy to over-do without even realizing it.
