Ever since I was a child, my mouth has caused me trouble. I'm not a bad person, but I have a hard time learning when to stop saying things to others.

    My mum has told 1 again and again, "Robert, you bad words are hurting me. 2 you continue to be this rude, you will get into big trouble."

    It has been a problem at school several times too. One day, in English class, I was working on my homework when I heard a classmate 3behind me. It was Nathaniel, who liked doing that as usual.

    I thought of what my mother had said to me and 4 nicely, "Nathaniel, would you be quiet?"

    However, Nathaniel kept saying something to the boy next to him loud. I5shouted, "Nathaniel, shut up!"

    6the next five minutes, we threw hurtful words at each other.

    "At least I don't have an ugly lazy eye like you!" I cried out.

    I knew this would make him 7 and it would hurt his feelings and shut him up.

    What I said filled him anger. He ran to my 8 and tried to catch me as he shouted, "That's it! That's it!"

    Surprised at his reaction, I sat back in my seat. I had9seen Nathaniel act like this before. Later on, we were taken to the teachers' office. There, Mr. Black. Our English teacher, told us to 10the problem between us. Only then I finally found that 11I hurt someone physically(身上), he can finally get healthy again. But when I hurt someone with my 12, sometimes the pain never goes away.

    At the end of the discussion, I said 13to Nathaniel.

    When I went back to my room, I began to14 how often what I said hurt others. I'll remember what my mom said to me and learn when to keep my 15closed.
