     On the first day of my sixth grade, I saw one little girl called Amy on the school bus. "Don't talk to

her," said Lauren, who sat beside me, "or they will make fun of you."

     Amy had many physical differences-lots of reasons for other kids to make fun of her. Her eyes

weren't straight. Her glasses were too big. And she had really ugly teeth.

     Every day as we drove to and from school, kids would insult Amy, "God, what a strange face! Stop

looking at me!"

     I had to be in silence. After all, I didn't want them to treat me in the same way.

     But while I was insulting her, my heart ached for the girl. I could see that she was so ashamed

(感到羞耻的) and alone. Then I wanted to stand up for her. I just didn't know how to stop my

schoolmates until the night of our class skating party.

     Our whole class was there. Amy was there, too. Amy didn't know how to skate, but I could see

how much she wanted to have fun like the rest of us. So I skated over to her and took her by the hand.

She just smiled, and was very excited.

     The next morning there was much news about Amy and me skating together. But nobody laughed at

her or me. And they didn't for the rest of the year. I never heard from Amy again after the school year.

But I've always hoped that I changed her life for the better.
