Lunch or No Lunch, That is the Question

I went to a play where I use to teach. Before I left I made lunch for my mother and left it in the fridge covered with clear wrap. I've done this several times with no problem. When I got back today her lunch was right where I left it. I asked her about it and she said she ate something, but couldn't remember what. As long as she's not hungry I guess it's all right.
I left my grandson-in-law here. He was outside painting a fence for me. I was a little worried about her forgetting and being worried about a man here, but that seemed to go OK. She thought he just got here (when I called in to check).
One never knows!
