My third grade bully

Back in my days of third grade I was a good student. I had all A's and my teacher liked me. In the midst of all the good things there was one issue I had. This girl decided that she did not like me and she was mean to me every day. The sad thing was, was that I was the ONLY person she was mean to! Everyone else thought that the girl was just one of the nicest people in the world. I did not understand why it was just me that she was picking on. I tried to be as nice as I could to the girl, but no matter how nice I was she was still very hateful towards me. She would take my pencils, tell me how bad my work was, or just say mean things to me (like telling me to shut up and such). I tried to tell the teacher, but the girl had the teacher fooled to. I felt really alone. Why was I getting picked on when I had done nothing wrong. No matter how mean the girl was to me I did what my mom told me to do and that is to "Kill her with kindness." Too bad it was not working. This went on for what felt like forever but it was actually a couple of months. Finally I just could not take it anymore. I begged my mom to please do something. My mom went to the school and had a talk with my teacher. My teacher could not understand because she thought that the girl that was bullying me was so sweet. The girl had everyone fooled. My mom had a long talk with my teacher, explaining to her that I would not make this up. She asked my teacher if I had ever made up a story before. Of course the answer was no. The next day in class my teacher asked some students if they had seen what the girl was doing to me. Most of them said no because the girl was so nice to them they did not think she could be mean to me. Luckily my best friend stood up for me and told the teacher that it was true I was being bullied. That moment my teacher took the actions she had to to fix this issue. Finally someone saw the truth. Everyone saw the girl in a different way than me because she was so mean to me and yet so nice to everyone else. Then the truth was revealed..she was jealous because she thought the teacher liked me better. When she realized that she could bully me and get away with it, she kept on because she thought the teacher liked her better since the teacher would not believe that I was being bullied. After that the bully-girl was seen in a different way. However I was still trying to look at her as a girl who needed a friend so I was still nice to her.
