    A driver stopped his car on a street side to have a rest. As he lay down in the seat and closed his eyes, a person came up and knocked at the window to ask the time. The driver opened his eyes and looked at his watch. “It's five past eight.” he said. Then he went to sleep again. But soon he was waken up again because a second person was knocking at the window. “Excuse me, what time is it now?” He asked. The driver looked at his watch again, and told him it was half past eight.

    In this way, the driver thought he couldn't have a good rest, so he wrote a short note and stuck(贴) it on the window for all to see. It said, “I don't know the time.” Again, he lay down in the seat for his sleep. A few minutes later, a third person came and began to knock at the window, “Hey, sir.” He said, “It's a quarter to nine.”

    A young man worked very hard at his lessons. He was too busy to have a rest. At last, he became ill, so he couldn't go to sleep. Every night, when he went to bed, he closed his eyes and tried to sleep. But he always stayed awake and couldn't fall asleep.

    After some days, he decided to see a doctor.” I just can't go to sleep at night. What should I do? Could you please help me?”

    “I have a suggestion(建议)，”said the doctor. “Try counting numbers. By the time you reach one thousand, you'll be asleep. I'm sure of it.”

    The next day the man returned to the doctor's office. “Well,” said the doctor, how are you today? Did you try my suggestion?”

    The man still looked tired. “Yes,” he said, “I tried counting one, two, three-up to one thousand. But when I reached five hundred and sixty-nine, I began to feel sleepy. I had to get up and drink some tea so that I could go on counting up to one thousand. But then I still couldn't fall asleep.”

    One pleasant evening, I was holding Grandpa's hand and taking a walk in the park. "Where are the peanuts? Give me now!" He suddenly said. How I wished I had some with me! "William, the monkeys are taking long to come out today. Wait till they smell the peanuts." I knew he was lost in one of his memories again. I remembered the stories he told me of how he fed the monkeys when he was a kid. Then, he saw the goldfish! He acted as if he was seeing them for the first time.

    Poor Grandpa! He fell ill with Alzheimer's disease (阿尔茨海默症) last year. The doctor said it was a progressive brain disorder which could destroy (破坏) a person's memory. The patient might also not be able to make reasonable judgments (判断). The saddening part was that it was a lifelong disease. But when my parents invited him to stay with us, he refused and said he liked living alone. One day, he forgot to turn off the fire after cooking porridge. Luckily, one of the neighbors came to help him before the fire could spread.

    It was then that my parents brought Grandpa to live with us. Often, he would forget my name and ask me who I was and what I was doing in his house. Each time I would answer softly, "It's me, Ray, Grandpa!" Even if he had forgotten who I was, he would always be my beloved grandfather.
