There is another interesting short story that i read from the cappucino and sucess 101 short stories' book

There is a king with his wise advisor...
the advisor favourite word is "EVERYTHING HAPPEN FOR THE GOOD".
One day, the king and the advisor went for hunting and unfortunately for the king, the arrow hit his own foot.
the King ask his advisor opinion and he replied by saying "EVERYTHING HAPPEN FOR THE GOOD".
The King get angry and order him to sent to the prison.
Once more the king ask his advisor opinion, and once more the advisor reply, "EVERYTHING HAPPEN FOR THE GOOD".
then the King left him alone in the prison.
A day after, the King went for another hunting trip without his wise advisor on his side.
Again another bad thing happen to him.
He had been captured by the cannibal peoples to be their meal.
before they cook the King, they do some checking on him..
and they found that the foot have some wound..
and according to the cannibal tradition, they wouldnt eat any imperfect people, therefore, they threw him back to the jungle.
now the king realize what the Advisor told him is definetly true..
