During the last fifteen years of my mother's life she suffered with Alzheimer's disease. Until then she had been a bright, __51__ woman deeply interested and involved in the world around her. I would go home to visit her in Virginia and she would look at me in a(an) __52__ way and ask, "Who are you?" I would answer, "I'm your son." "Where do you live?" She would ask. "In California," I would tell her. "Isn't that interesting," she would say, "I have a son in California."
She seemed __53__ forgetful and confused at the beginning of the disease, __54__ later on she would go __55__periods of intense anxiety. She would pace through the house she had lived in most of her life __56__ uneasily that she wanted to go home. Or she would leave home and wander away if she were __57__ for a short time.
Hoping to please her and put her mind __58__ I would take her for a drive, visiting sites where she had lived as a __59__. In the yard of the hillside house in Shipman I sat in the car and admired the view of the old oaks and long green lawn. I __60__ my mother there as a little girl playing with the pet lamb she had been so fond of. I looked to her for some __61__. She shook her head and said, "I want to go home." Over the years I have decided that what my mother was calling home was not a __62__, but a time. I suspect it was a time when she was much __63__, when her children were still underfoot, when her husband was still vigorous and attentive.
Watching my mother's suffering set me wondering __64__ I would have in mind if someday I couldn't find __65__ and wanted to go there. In this family we tend to be long-lived and we grow fuzzy (糊涂的) minded as the years go by. At eighty I have already noticed some __66__ symptoms. My doctor says the forgetfulness is only __67__ and that it comes with age. Still the fear of Alzheimer's is haunting there. Someday __68__ and when I become even more __69__ minded than I am now, unable to drive and unable to tell you where "home" is, my dear son, I expect I will ask you to take me home, I know you will do your best to find the place I need to be. I leave these notes for your __70__.
