That's really sweet of her. She could bring the woman by each week to see them and it would be a new trip each time! ;o) The pictures will be nice, though. My sister did that for Mama all the time. They were her only 'memories'.
I remember visiting the Alzheimer's home with Zulu... They never remembered me coming before, so it was always new.. and that makes it easier for a visiting dog that didn't know very many tricks :~D
