This is not a Christmas Card, this is a cry for help.
I can only imagine what the back of the card says: "It's been a quiet year for your old friend Mary L. Gray, but that's the way I like it. Really. I don't get so many visitors, but that's all right. Visit if you have the time. I don't want to be a bother, though. Anyway, this way I've got plenty of time to do a very thorough job of shoveling. Yes, sir, Mary L. Gray can sure shovel a walk."
Mary L. Gray needs companionship badly. Maybe she should get a dog.
