A Wolf saw a Sheep by a small river and wanted to eat him. He shouted, “I can’t drink this dirty water! It’s too dirty! You have  made the water dirty. You put your dirty feet into the water!” •“No, I didn’t  make it dirty,” the Sheep answered. “I didn’t put my feet into the water.  I drink with my mouth and not with my feet. Look! My feet are not in the water.” •“OK. Than it was last year. You put your feet into the water last year!” the Wolf shouted. “And you made the water dirty.”

    “But I am only four months  old,” the Sheep said. “How could I put my feet into the river a year ago?”

•“If it was not you, than it was you brother or your  father,” the Wolf shouted and jumped on the poor (бедный) Sheep. But the Sheep ran away. And the Wolf fell into the water.
