完型填空。
     I've always had strong opinions of how love should be expressed, but others had their own ways of
showing care.
     What I   1   most about visiting my boyfriend's parents is the loud tick of the clock in the dining room
as we   2   ate our meal. With so little conversation I was quick to   3   his family as cold. When we got
into the   4   to go home, his father suddenly appeared   5  , he began to wash his son's windscreen. I could
feel he is a caring man through the glass.
     I learned another lesson about love a few years later. My father often   6   me early in the morning. "Buy
Xerox. It's a good sharp price," he might say when I answered the phone. No pleasant   7   or inquiry about
my life,just financial instructions. This manner of his   8   me and we often quarreled. But one day, I thought
about my father's success in business and realized that his concern for my financial security lay behind his
   9   morning calls. The next time he called and told me to buy a stock, I  10  him.
     When my social style has conflicted with that of my friends, I've often felt  11 . For example, I always
return phone calls  12  and regularly contact with my friends. I expect the same from them. I had one friend
who rarely called, answering my messages with short e-mails. I rushed to the  13 : She wasn't a good friend!
My anger  14  as the holidays approached. But then she came to a gathering I  15  and handed me a beautiful
dress I had fallen in love with when we did some window-shopping the previous month. I was  16  at her
thoughtfulness, and regretful for how I'd considered her to be  17 . Clearly I needed to change my expectations
of friends.
     Far too often, I ignored their  18  expressions, eagerly expecting them to do things in my  19 . Over the
years, however, I've learned to  20  other persons' love signs.
