Once upon a time there was a deer. His name was Orni. Once Orni looked into the lake and he saw his reflection.
- I have so beautiful horns! But my legs are so thin! - Orni hadn't seen the lion behind him. When the deer turned back his head, he began to run. He ran so fast, that the lion began to lag. But his big horns caught on the limbs, and the lion caught him up in a drumbeat.
- Ah, I was so silly, when I didn't like my strong and long legs, that could save me. And I bragged of my horns, which brought me to death. - That's all that Orni had time to think about.
