Once upon a long time ago, there was a long and lonely lane. You'd be surprised at how long and lonely it was. Not a dime nor deer for a hundred miles either way, maybe more but no one ever knew. On either side of this lane was a dark and sinister forest to the right, and to the left was a beautiful meadow with a rippling lake right on the horizon.
Beautiful and blackhearted creatures inhabited the dark and sinister forest to the right. These creatures were so corrupt and dire that not a soul went near them. These creatures had two arms, two hands, two thumbs, two legs, two feet, two eyes and two lips. Their very beings were filled to the brim with darkness. They were distracted from the light and drawn into temptation.
However, there was a man who had done so many awful deeds; some too horrible to even describe. But there was something different about him. He felt sorry for what he had done. Somehow through the mud that covered his slimy skin, the light entered his eyes and he was sorry. He gouged out his right eye and cut off his right arm, keeping only the left. Why keep a reminder of something so dark?
The man then crossed that long and lonely lane, with only his left eye and left arm, knowing that he was much better of without them both.
The moral of that story is that if your drawn into temptation, you should come out a better person than when you were before, even if you've lost something important along the way.
