#PI# #PI# #PI# When I was a child, we learned a text called "The Boy Who Cried Wolf." When the shepherd boy shouted that the wolf was coming, the adults believed him and went out to hunt the wolf, but there was no wolf. Later, the shepherd boy shouted again that the wolf was coming, and the adults chose to believe him again and went out to look for the wolf, but still, no wolf came. Therefore, the adults became angry and no longer believed the shepherd boy. When the wolf really came, the shepherd boy shouted that the wolf was coming, but this time the adults did not believe him, and as a result, all the sheep in the pen were eaten by the wolf.
