I think why your granny doesn't want to leave the village is because she's strongly connected to it. That's likely where the key memories of their live were made. Staying there allows them still hold on to the memories, and their old lives. Also, for old people, it's generally more difficult to pick up their entire lives and move to new places.
I agree with your conclusion. We don't have to be there to care for them, and we definitely don't need to put them in a retirement home. What matters is that we ensure they're comfortable and taken care of, wherever they are.
Yeah, I think same too. She had all her kids there and have all her assets there too.
It's the best way really!
