In the past, I always thought that being a teacher was an easy job. But I changed my 【A1】when I became a part-time teacher. About four years ago, Richard asked me【A2】I could help teach his students how to make a website about themselves. 

I【A3】because computer is what I do well and I didn 't think teaching computer would be that【A4】 . 

But when I taught Richard's class, some of the students【A5】 with their friends while I was explaining how to do something. At first I just got angry with them,   【A6】Richard taught me to think why they were doing this. He said that if he was 【A7】 a lesson and the students were not listening, then he was angry with 【A8】  for not making the lesson clear or interesting for them. I told him that I didn't 【A9】his idea. He then asked me if I had ever 【A10】the same thing. That made me stop. Of course I had! 

If any of my past teachers are 【A11】 this, I want to say sorry if I sometimes played around in the class 【A12】 you were teaching. I didnt think how that would make you feel. I promise I will do my best to be a good【A13】 in the future. Please help us when we don't understand and most 【A14】 , don't be quick to be angry when we fail. 【A15】of us are perfect but with your help we can be successful.
