The Wolf had not eaten in some time and thought about ways that he could satisfy his hunger.

He decided to put on a white coat and a badge and a stethoscope and headed out to the neighbourhood which is where all the sheep lived. 

The Wolf walked around smiling sweetly at the sheep and let them know that he would be happy to help them and give them medicine to make them feel better.

“I know exactly what you are” – announced the Shepherd stepping out from behind a tree – “I am sure that all the sheep would happily take what you are offering – but no matter how well you disguise your appearance and your intentions, I know that they would remain far better if they don’t take what you are offering, for I know full well what their fate would be if they did“.

And the Moral of the Story is:
What sounds good at first, may later prove not to be good for you at all.
