There is a story that I heard today, that I just had to re-tell. I hope I get it right.
There was this little boy who was acting out, being destructive and just being naughty. He was in a room with his Granfather. The Grandfather took his Grandson aside and told him that he understood what the boy was doing and that he had done the very same thing when he was young.
So the little boy asked what he meant.
The Grandfather said that he had two wolves in his head. One was a good and kind wolf who was considerate of other people, honest and always tried to do the right thing. The other was a bad wolf who was, destructive, mean, dishonest and always got in trouble. He then told his Grandson that they were always fighting to see who would win.
The little boy, fascinated, said "which wolf won?"
The Grandfather said the the wolf that won was the wolf that I fed.
