My mother only had one eye．I never wanted her to show up at my school．One day during my primary school，I was terribly ill and my mother came．"Your mom has only one eye!"Some of my classmates yelled．I wished my mother would have just appeared （消失）．"If you embarrass me，why don't you die？"I shouted at her，taking no notice of the sad look on her face．My mother just handed me some medicine and left without saying anything．
At that time，I didn't think I had hurt her feelings very much．That night I saw my mom crying in her room．Even so，I hated her tears from one eye．I made a decision：I must study hard and leave my mother．
Years later my dream came true．It was quite successful．I never thought of going back to see my"ugly"mother until one day I got a letter．
"My son，I'm sorry to have have only one eye．When you were little，you had an accident and lost your eye．As a mom，I couldn't stand watching you live with only one eye．So I gave mine to you．I was never angry with you and I never regretted it because I love you．
I cried out aloud．Only then did I realize how beautiful my mom was!
