What is the conflict in 'The Boy who cried Wolf'?

The boy is up on a hill with sheep at night and he thought it would be funny to shout that their was a wolf so he did and the people that heard him came running to his rescue so when there wasn't a wolf there they were mad and went home. The next night he did the same and again the people came running and then went back home but when the third night came there was actually a wolf and when he shouted for help no one came because no one believed him so he died.
