There was this bar and in the bar there was a magic mirror.
If you told a lie it would suck you in.
One day a brunette walked into this bar. She walked up to the mirror and said 'I think I'm the most beautiful woman in the world' and it sucked her in.
The next day a redhead walked into the bar. She walked up to the mirror and said 'I think I'm the most beautiful woman in the world' and it sucked her in.
Then the next day a blond walked into the bar. She walked up to the mirror and said 'I think...' and it sucked her in.
It's so very wrong. In fact, isn't it one of the 7 deadly sins? The fourth one, actually. It is: Lust: is an inordinate craving for the pleasures of the body.
See? In the 10 commandments :7. “You shall not commit adultery."
So, yes, it IS very wrong.
