Recently, my Mom (87; Alzheimer's; lives with my sister) spent a week in a nursing home, as a kind of trial run. When my sister and brother-in-law went to pick her up, they got out into the parking lot, and brother-in-law asked her how she liked staying there.
"I didn't stay here", she replied, a little huffy. "I've never SEEN this place before."
Man oh man. An entire week, she had just left the place, and she had no memory of it at all.
That Alzheimer's is some weird shit.
