My oral report

Today, it is my turn to have the oral report.
Last Wednesday, we just talked about cheating. Some of the words that Ms Christine said left me with a deep impression. I still remember Ms Christine said, ’If one person does something like cheating, I will not use him or employ him.’ Maybe what I said is not the same with what Ms Christine’s words, but it really make me feel upset, because I did some foolish thing ever before.
That was when I was in middle school, near the final exam of that term. While we were busy reviewing in biology class, my teacher just sat in front of us and set exam questions on the computer. After the class, she deleted the document of the exam questions, but she forgot that the document was still in the dustbin. What I did was just removing it to the desktop, even not looking at one question, but after my teacher knew that, she called me to her office and said she no longer believed in me. I tried to explained, but nothing worked. Though I was not punished, everytime I recalled this, I felt really regretful. Till today, I even do not know why I did that at that time. Maybe for the impulse at that moment, but I can not deny what I did. The only thing that I can do is to correct myself and not to do it again, but I do not know whether I have the chance and whether my teacher will believe in me for a second time. I can promise I will not do such kind of things again, but who will believe me? I have no answers. I am really eager to know whether the person, who did something wrong like me or even worse, deserves trust. I hope I can get the answer today, from Ms Christine and from all of you. Thank you for your listening.
