the reason it's not cheating to me is because i never go into a task with the intention of cheating and trying to get away with it. if i am given a task and am unable to do it or screw it up, yeah i fucked up, but i'm not going to cheat and try to hide that mistake from him. i confess and tell him what happened...therefore it is not cheating. it's all about intent in my opinion.
if you are given a task and make a clear conscious decision.."no, i'm not going to do that and i'll just lie about doing it" then hell yeah that's cheating. hands down.
