My younger sister Joy was fighting her final battle against cancer. I wanted Joy to go into a nursing home
(疗养院), but she didn't want to spend her final days there. I couldn't be with her all the time, and she had no
other family. God, who would watch over her?
     Joy and I had come from a medical family. Mom died when my sister was four. Dad was a small-town
general doctor in Glenview. His concern for his patients was wholehearted. Sometimes Joy and I had felt
overlooked, expecting the attention he seemed to reserve (保留) for his patients. But no matter how busy he'd
been all week, Dad would stand on the stairs every Sunday morning, polishing (擦亮) his shoes for church.
    I called Dr. Croghan, Joy's doctor, hoping she could persuade (劝说) Joy to move into the nursing home.
"Your father also called," she said. The signal of her phone went off, and the doctor suddenly hung up before
I could correct her.
    Three days later, Joy died at home. I called Dr. Croghan to thank her for all she'd done. Then I mentioned
the phone call. "It had to be someone else who called you," I said.
     "He said he was Joy's father clearly," Dr. Croghan insisted. "He talked about her case and understood all
the medical details."
    Who could it be? My dad died three years ago; it couldn't have been him. Maybe it was one of the
neighbours or my father's former patients, many of whom were grateful to my father. Who could it be?
I wonder.
