I cheated once in 8th grade, this kid next to me and I hadn't finished our big science homework and he told me we should fill in each other's sheets, with a few mistakes here and there of course. Throughout the day I just kept feeling like I shouldn't have done that, so by the time I got home I was crying and immediately told my parents. The next morning we went in to talk to the teacher, I told him what happened, apologized, and I got to re do the paper because I was honest, while the other kid didn't, and got a detention. Needless to say he never talked to me again, even though the teacher made up a bogus story about the substitute spotting us.
