[EX Q]: Article: If you have a watch, don't go to a watchmaker's unless something is wrong with the machinery. Once I had a beautiful watch. And it had kept perfect time. But one night it happened that I forgot to _ it _ . Next morning I went to a watchmaker as I wanted my perfect watch to be set by the exact time. He examined it and said, "The regulator must be pushed up as your watch is four minutes slow. I tried to stop him from doing so, but he didn't listen and pushed the regulator. My beautiful watch began to gain. It gained faster and faster day by day. By the end of the second month it had left all the clocks and watches of the town far behind. I could do nothing but take it to another watchmaker to be regulated. I expected him to regulate the watch at once, but he asked me to come in a week's time. When at last I got my watch back from him, it began to slow down. And I failed to be in time for trains, business affairs, and even missed my dinners. Now I went to a third watchmaker. When I was waiting for him to repair my poor watch, he took it to pieces and said that he would try to finish this work in three or four days. What I could do was to nod my head. After that, my watch went for half a day, and then stopped. So I kept taking my watch from one watchmaker to another. But each watchmaker disappointed me. My watch had cost me two hundred dollars, but I paid for repairs more than two hundred. At last I decided to buy another watch, which I did.

[EX Q]: Article: When I got up, Mom was already awake. I could hear her doing something in the kitchen. It's was my birthday, and I was afraid. What if my husband had neglected to take Mom shopping for a card? Once Mom found it was my birthday, she would be sad that she had forgotten and had nothing to give me. She even can't remember what we did two hours ago because of dementia . Birthdays are not a big deal to me. I hate growing older. I don't mind if Mom forgets my birthday as long as she still remembers me. That someday she might not recognize me has been my biggest fear ever since Mom got dementia. I can't imagine anything more devastating than being forgotten by my own mother. When Mom was diagnosed with vascular dementia seven years ago, I was told she did not have Alzheimer's disease . I hoped that meant she would never forget her family. But as Mom's dementia progressed, I realized that I had no idea whether vascular dementia could be as bad as Alzheimer's. I really didn't understand the difference. The sleeping house was quiet except for the sound of Mom washing the bowls left last night in the kitchen. Will Mom live long enough to forget me? Will the day come when she no longer worries about remembering my birthday because she no longer knows that I exist? In the kitchen, Mom heard me come near. She hurried to the door, face ringing with smiles. "Happy birthday to you," she sang. We laughed as I hugged her tightly, and both of us were very surprised that she had remembered. Moments later she said, "Oh, there seems to be something here for you." She brought me her card. My husband did, after all, take her shopping. The birthday-for-a-daughter card was filled with expressions of love in pink.
