I suppose I cheated once on an assignment. Our 11th grade psych class had to take notes during lecture, and somehow I didn't get the memo, maybe I went to the restroom during those two crucial minutes, but we were also supposed to type them & turn them in the day of the test. Whoops. So I totally didn't know to do that. You know you fear being in such a dreadful situation, where your peers scramble to complete the homework the morning and you, ONLY YOU, didn't know it was due. So, I'm like, WOAH WHAT OH MY GOD WHAT DO YOU MEAN WE HAD TO TYPE OUT THE NOTES -GOTTA GO FAST TO LIBRARY-. And so I went on a computer to type & print out something. Then, a classmate approached me with her USB drive and asked for me to print her assignment. Uh yeah whatever, I'm not really friends with her, but I suppose I'm too nice. So I opened her document and let her print it. :/ I then had the dumb idea to use her typed notes, make some changes, but my teacher noticed it and had a talk with me not to do it again.
I'm the one people cheat off of, though. One time in middle school, the teacher caught a student looking at my homework in class. I was about to get upset over it, but the girl admitted to cheating and that I did not permit to it, noble of her to do that bit, anyway.
