     One Sunday morning in June 1959 my mother walked into my room. "Surprise!" she said, proudly holding

up a yellow dress ."I made it just for you. What do you think?"

     I bit my tongue. How could I tell Mom it was the ugliest dress I had ever seen?

     "It's perfect for church," my mother continued delightedly. "I wish someone had made a dress like this for

me."

     Too bad you can't wear it, I thought. But I knew Mom had spent a lot of time on the dress. No one should

refuse.

     Unwillingly I put it on.

     All through church I prayed (祈祷), Lord, let me get out of here without anyone seeing me. Especially

Dennis Pearce, the boy I had a crush on, one of the coolest boys at Neptune High School. Although we were

in some of the same classes, Dennis had never taken any notice of me. Every time I got near him, I became

tongue-tied. |

     At the end of the service I rushed for the door. But I had to wait on the steps while my parents chatted with

their friends. Just a little while longer…Then out of the corner of my eye I saw the Pearces coming near. Before I could escape, Dennis was right beside me.

     I started talking, hoping if I kept it up he wouldn't notice my ugly dress."I'm going to college in September,"

I said.

     "That's great," Dennis replied "I got accepted to police academy (学院)."

     "Wow!" I said. Somehow I kept the conversation going. The next thing I knew Dennis had asked me out on a date!

     We courted (恋爱) through college, and eventually got married. Months after our wedding I asked Dennis if he remembered the day he had first asked me out.

      "Certainly I do," he said."You were always quiet in school. I didn't think you'd be much fun. But you were

so lovely when we talked on the church steps, I wanted to get to know you better." Maybe that yellow dress

wasn't what I would have chosen, but that day it was the perfect dress for me.
