My friend stole my work. We had 13 days to write a history essay and I helped him write 2 paragraphs. The day it's due, I let him have my incomplete rough draft but he finished it. He said he would try to change my NEAT writing into his messy one, I say ok. He only changes only about a sentence worth of writing. I thought he was going to paraphrase what I wrote into his essay. He turns in MY work as his. I try to convince him that we'll get caught but he just says to not worry. It's been a week and want to tell the teacher but I don't want my friend to get mad at me or him to tell other people. I'm really worried that'll get in trouble with the principal for cheating, because the essay was considered a test, which I didn't know. Should I try to convince him into telling the teacher or just tell her myself? This is the simple version of what happened
