At a medical clinic in Waterloo, Ontario, an elderly woman sat on the edge of a waiting room chair singing the Celine Dion tune "My Heart Will Go On." Other than a slight rhythmic rocking of her body to the Titanic theme song, she kept still, with her arms crossed elegantly over her chest. With little effort, she was able to send her sweet，high-pitched (尖声的) voice exploding into every comer of the clinic.
I had fun watching how people reacted. There was a lot of changing in seats, but mainly they awkwardly looked away and tried to pretend there was nothing out of the ordinary going on.
I was there with my father, who was getting a routine blood test, when the woman arrived. She settled into the seat directly across from my dad. Because she was so tiny, she was forced to sit on the edge of the chair so her feet could touch the floor. The position made it seem as though she were sitting forward to engage in conversation with him. She smiled at him, and he smiled back.
I was concerned about how my dad would react to the possible invasion of his space. He was 77 at the time and had been living with Alzheimer's (老年痴呆症) for several years. He was a brilliant and shy military man. When he was healthy，he tolerated people's eccentricities (古怪) dutifully but with silent disapproval. He considered it wholly bad mannered to bring too much unnecessary attention to oneself. Since Alzheimer's has a tendency to cause damage to a person's patience and self-control. Dad had got into a few challenging and unpleasant situations in the past. I couldn't help but think that this little woman was playing with fire.
Her singing began gently, like a quiet hum. I glanced over at Dad. His smile was gone, and he was staring right at her. She was staring back. I couldn't read his expression, but it seemed to be something like confusion. This wasn't an unusual state for him.
