Continuing thanks, folks. Grandma Jo's a tough one. Against all expectations, she rallied some today, squeezed my Dad's hand and again showed some level of responsiveness and awareness.
Oh, and one of those stories that sends a chill: two weeks ago, Grandma Jo was visiting her sister. Her sister, hearing some activity in the kitchen, came in and found Grandma there.
Grandma said, very calmly, that she'd had a dream. "I can't sleep. Bob said he's ready for me."
"Bob" is my late grandfather.
