Comparing having your mother at home to having a dog at home is a low blow even for Michael. After the grief the family and the now, nonexistent John gave her for leaving, this is just an added insult. If I were Elly, I would turn around and call Sally saying, "You know I am suddenly feeling a lot better. You might say…
1. My illness has gone to the dogs. I am feeling diff-fur-ent.
2. I was feeling ruff, but now I am feeling more paw-sitive.
3. I thought I had stepped over to the bark side, but now I am ready to raise the ruff.
4. I think that person who called you before was my doggleganger.
