Wolves and sheep
Wolves and sheep have been fighting for thousands of years, in the eyes of the sheep, wolves are born mortal enemies, the number of grievances on the surface, the Wolf ate a lot of lost lambs, but in fact the shepherd also slaughtered a lot of wolves, neither side took advantage of
After much deliberation, the wolves and the sheep finally decided to bury their differences and live in peace. As a sign of good faith, the two parties held a solemn exchange of hostages. The wolves gave up their pups, and the sheep gave up their dogs. From then on both sides lived in peace.
A year later, when the wolves had grown up and showed their fierce nature, they killed many of the lambs while the shepherd was away, and the wolves ran back into the forest with the lambs in their mouths. As a hostage, the hounds were attacked by wolves in their sleep, torn to pieces, and became a meal for the wolves.
The lesson of this story is that we can only fight resolutely against an enemy that does not keep its word, without a trace of illusion.
