I cheated once in eight grade to test out something my friends told me about the history teacher. They said that she only reads the first two and last two paragraphs of an essay question, so, before the test started, I wrote out the answer to the essay (there was only one possible essay question) like I normally would, but then wrote a bunch of crap for the remaining paragraphs. During the test, I handed in the fake one that I wrote before the exam. And my friends were right. I got an 8 or 9 out of 10 on the test

The bitch doesn't even read your full answer
During our normal class finals, I would sometimes help my friends out. I never had the need to cheat because I find everything so easy - even though I don't study - and my friends hate that about me, so why not help them out
As for relationships, no. If you ever feel like cheating, then why be in the relationship in the first place? I'd rather end it.
