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 lively 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.
