In the past, I always thought that being a teacher was an easy job. But I changed my 31___when I became a part-time teacher. About four years ago, Richard asked me whether I could help teach his students how to make a website about themselves.

I 32___because computer is what I do well and I didn't think teaching computer would be that hard.

But when I taught Richard's class, some of the students chatted with their friends while I was 33___how to do something. At first I just got angry with them, but Richard taught me to think why they were doing this. He said that if he was teaching a 34___ and the students were not listening, then he was 35___ with himself for not making the lesson clear or 36 ___for them. I told him that I didn't 37___ his idea. He then asked me if I had ever done the same thing. That made me stop. Of course I had！

If any of my past teachers are reading this, I want to say sorry if I sometimes played around in the class when you were teaching. I didn't think how that would make you feel. I 38___I will do my best to be a good student in the future. Please help us when we don't understand and most 39___ , don' t be quick to be angry when we fail. None of us are perfect but with your help we can be 40___ .
