I've never been this kind of situation I'm positively certain that I will never do such a thing. I don't like cheaters nor do I like the idea of cheating. it's wrong, wrong, wrong!
Fortunately, I've never been in that situation, nor do I ever plan on being in it. There is just something wrong about doing that which upsets me to the point that If I did it, I wouldn't be able to look myself in the mirror. Besides, I live the lame motto of "Do onto others as you'd want done onto you."
