Yes, I know I like the virgin mary, but the teacher for that class is my mom old friend and he wants me to tell her I cheated, and I pretty scared because my mom is very serious with his class. SO... please help!
Suck it up, and put your big girl panties on and tell her. Don't sugar coat it. Just tell her what you did and be truthful. You'll earn a little more respect being upfront and honest about it.
