The mother of my sister-in-law developed Parkinson's. Late in life, she could not recognize her own reflection in a mirror. If she saw herself, she was afraid. So there were no mirrors in her little suite at the care center.

And yet, when we visited, our conversations were intelligent and pleasant. She remembered me, whom she hadn't seen for 25 years. So don't give up on a person just because one part of the brain is damaged.

One day my own mother, who about 75, said, "Inside of me, I am not the old woman I see in the mirror. Inside of me there is an 18-year-old girl." So when we went out to eat, we chose the places with the cutest waiters so we could be boy crazy again.

Parents - enjoy them while you can.
