Two sides of the same card really.

There is no such thing as a 100% honest person. If they exist they are riding unicorns.

We all lie about trivial things. I recently read where the average person lies three times in a five minute conversation. And, of course, there are always the white lies we all tell to keep out of trouble.

Cheating and lying are both evading the truth. I don't see much difference. I don't want either one in my life. The Catholic church had a few things right, there are "sins" of omission and "sins" of commission. Both are not behavior I want to put up with.

Personally, I find them equally repugnant.
Cheating requires lying.
Lying about "trivial things" is indicative of larger issues.
