They found an apartment in an "independent living" facility about 15 minutes from my parents, 30 from my aunt, 45 from my uncle, and 5 minutes from my brother--the favorite grandchild.
My grandfather is really excited about it and wants to move in yesterday. He was telling me about his plans to turn the second bedroom into a den, which I guess is the old-man version of a man cave. My grandmother thinks it's nice, but wasn't ready to give up her life at the beach. She'll come around.
They'll get 2 meals provided per day, and maid and laundry service once a week, and there are doctors and social workers on call. It's not full-out assisted living, which is good since they're really not that bad off at this point. I think they'll get to maintain their social lives, but not have the stress of cooking and housework, and they'll be close to family if anything bad happens.
