Dear Amy, I have a problem and I'm writing ask you 1 for art advice. This is a secret, so I don't tell anybody else. 2 My cousin and I used to getting along very well and 3 we were good friend. We were planning to spend 4 part of the winter holiday together, but now 5 I don't think I want to invite her home. 6 Recently I has discovered that he's started to tell 7 lies. When I told him this was wrong to tell lies, 8 but he just laughed at file. The problem is, should I 9 tell his parents or his teacher, or should I keep quietly. 10
