Amy and I had been best friends since primary school and spent almost every day with each other. Sometimes, other children said we were no fun because we were both very academic（学术的） and liked to study, but we liked it that way. Both of us were very hard-working and always got good grades at school.
I thought we would be like this forever, however, our friendship was on the rocks recently.
One Monday, we had a surprise math quiz. I thought it was quite easy and was not worried about the results.
I must have sounded very proud of myself after the quiz, saying how easy it was and how I was sure to get a good grade. And many classmates looked at me with admiration.
The next day after class, my math teacher told me that I had the lowest grade in the class!I felt so ashamed and couldn't believe it；I must be really stupid to fail a simple math quiz!
Afterwards, I pretended to be cheerful and greeted others with a smile as usual, but Amy sensed something was wrong.
We went to wash our hands in the girls' washroom before lunch. She patted me on the shoulder and asked me what happened. Seeing her concerned look, I had to admit how badly I had done in the math quiz. I begged her not to tell anyone else, and couldn't help sobbing （啜泣）. She held me tightly, saying she would keep my secret, and cheered me up.
However, the next day, I noticed that my classmates were staring at me as I came into math class, when I went to sit down, I was shocked to find a piece of paper on my desk that said, ". . . Stupid Sarah got a D!" I was so upset that I felt like crying.

Then I began to cry, wondering who let out my secret—was it Amy?
When hearing the truth from Alice, I was shocked and couldn't wait to find Amy to apologize.
