One of my favorite movies is the Masterpiece edition of Pollyanna. There is a scene where Pollyanna brings home a stray dog. Her Aunt Polly asks "What possible use is a dog?" Pollyanna replies "Dogs just make you happy to be alive."
Monroe has been going with me to Elizabeth Scott on Saturdays to visit Mom. We barely make it into the lobby before someone wants to pet him - or just say "hello". Even those who do not interact get a smile on their face.
Laura and Lotty like to talk about dogs they have had.
Normally Mom isn't too happy when someone who is visiting her pays too much attention to others, but she doesn't seem to mind when Monroe is there. It makes her popular.
