The Viper and the File
One day a snake entered a blacksmith's shop. The snake was very hungry and wanted food. It looked around and saw an iron file. The hard file looked like a tasty meal. The snake came close to the iron file.
It started to bite the hard iron angrily. But the iron file felt no pain. The snake bit again, and its teeth broke. Its mouth hurt a lot, but it continued. The iron file laughed and called out.
"I cut even the hardest iron," it said. "You only hurt yourself, not me," it added. The snake saw its mistake and ran away. A fight against the strong only hurts us. Spit at the sky, wet your own face.
