Paul's Email Trouble with Peter

Hello my name is Paul. I am blogging about a problem with me and my friend. First I will tell you that in our school we get PDAs to use. My friend, Peter, isn't the smartest guy in town, and I sometimes email him the answers to tests and things, but I'm not sure I want to give him the answers to the next test, and I really feel guilty. I really want to help one of my best friends, but I don't want to get caught, because if I get caught, I will probably flunk the class and not be able to go on the big 6th Grade field trip to Catalina Island! I think Peter is playing a little too much video games and isn't studying, and I studied really hard for this test. I don't think it's fair that he gets to do anything he wants and still get good grades. Keep in mind that I have known Peter for a long time and we have been great friends, and I want to keep it that way! What do I do? Do you think I should continue to give him answers and still be his friend while taking the risk of flunking and not being able to go to Catalina Island? Should I not give him the answers, pass, be able to go on the Catalina trip, but lose one of my best friends forever? WHAT DO I DO????? help me!
