Years ago the following letter was sent to Ann Landers. It's a great image of true love:

Dear Ann Landers: I’m going to tell you about a love story that I witness every time I go to the nursing home to see my husband who has Alzheimer’s disease. Unfortunately, I know firsthand how this terrible illness affects family members, but I would like the world to know what love really is. I see a man who, I understand, has spent the last eight years caring for his wife who has Alzheimer’s. They have been married more than 50 years. He cooks and feeds her every bite of food she eats. He has bathed her and dressed her every day all these years. They have no other family. She lost a baby at birth and they never had any more children.

I cannot describe the tenderness and love that man shows for his wife. She is unable to recognize anyone, including him. The only things she shows any interest in are two baby dolls. They are never out of her hands.
