I’d like to tell you a story about my best friend Jane. Last week in school we had a big fight, and she didn’t 1 me. It all started when she asked me if she could copy my homework. I asked her why she wanted to do that, and she said that she had forgotten to do hers. I said I didn’t think it was a good idea. I said it would start a bad 2 and she should do her own work. She got really 3 at me and said she didn’t want to be my best friend anymore. I said that was OK and that I was sure she would 4 it. And she did. Yesterday she told me she was 5 . She said it was much better if she did her own work.
