5．When I was in seventh grade，I was shy，quiet and so was easily bullied（受欺负）．I used to get very sad about it．
In an art lesson，just while the teacher was out，a big boy took away my pencil case，threw it across the room and sat back down．Later on，he took my schoolbag and pulled it towards him．I pulled back the schoolbag from his hand and for the first time，I pushed him away and hit him on the back．In the rest of the lesson，I did nothing but imagined what was happening next．
Then the teacher came to me，"Peter，are you OK？"
"Yes，"I answered．
"No，you are not．Come to my office after class．"he said．
There we had a long talk．He made me smile and I became confident（自信） again．He taught me some life lessons，and said，"Get up，and don't be a bully yourself，but remember you are stronger inside，and if the bullies see this，they will stop．"
I remembered these words．From then on，every time as I walked to school，I put my head high in the way，and the bullying soon stopped．
