Cleaned out Grandpa/Pops yesterday morning. Oh what a crank. He's in front of the window in my folks' room. He prefers being closer to the window/sunlight. He gets more rambunctious and that to me is a good sign.
He follows my hand so I think he can register SOME things.
He quiets when Dad talks to him. It's awesome. Instead of saying "Shut that bird up!" he goes, "It's ok Grandpa, I know, you're alright."
