Cheating

I never cheat in my life. That doesn't mean I really think that's guilty. I just don't like it and I trust myself, that's all. BUT to the people who cheat, I think there are some reasons:
First of all, I guess they just didn't study hard and prepare very well for the tests, and also they want to have a good grade.
Secondly, they may just don't know what to do and very bored about their study
finally, they may just like me who don't think cheating is Really bad, they may just think that cheating isn't a big problem.
But I still want to say cheating shouldn't be allowed coz it will lead to big guilt in the future
