I know he complains a lot about school and having to do his homework but not in a million years did I expect him to cheat. That is so huge. Cheating is something that can follow you all the way through school! Teachers will know for many years that hes the kid who copied his Midsummer Nights Dreames say from someone else and theyll always have doubts about him. Well, I hope forhissake everything will be forgotten,but it looks as if hes going to have to suffer through a pretty hard punishment for now. I cant say Ive never thought about cheating before. There are lots of different ways that you could cheat if you really wanted to, but I wouldnt dare to do it. I would never want to get caught. It would be so embarrassing and my mom would probably lock me in my room for at least a year. Its so not worth it! I e-mailed Simon the other day and told him if he needed to talk that I was here. I wish hed have told me that he was having trouble with school. I could have helped him with it. I just hope he feels comfortable asking me for help next time he feels that cheating is his only choice! What do you think about Simons cheating? Think its no big deal or are you as shocked as I am? L
