Crap, I just hijacked my own thread! Oh well, guess it was going to happen eventually.
Anyway, I need to quit venting on this. I did eventually tell her, and it helped open up my schedule a bit. However, I'm going to need to do it again and push the boundaries even further, and that's why I'm trying to figure out reasonable expectations. I'll likely need to remove myself physically from the area at some point if I want to grow as a person, and, well... that leads to a turbulent chain of thoughts.
Fi isn't very good at perspective sometimes.
However, you do have a good idea. The only issue I see is that her definition of quality care doesn't match mine. When I suggested that the home does a very good job, and that she doesn't need someone to visit 6-7 days a week, suddenly she realizes that I'm a bit more heartless than she realized. From my perspective, grandma's about as happy there as she was at my mom's house, and to me that fits within reasonable enough that we deserve a break. Of course, you can see the trouble with sharing that with her...
Okay - end rant.
