There was a young prince who had a pet lion. The lion was his friend, but unfortunately, the lion was never let out of his cage. This made the lion feel sad because he thought that if he was considered a friend, then why was he not allowed out of the cage? 

Next to the lion's cage was a hyena. He hated the lion. One day, the hyena said to the lion, "if you are the friend of the prince, why does he keep you in a cage?"

The prince was about to answer, when the hyena cut him off and said, "The reason, Lion, is because of your big teeth." The prince laughed at this and said, "No, it's not because of his teeth!"

"Then it's because of your claws. They could kill the prince with one swipe!" the hyena said to the lion. The prince laughed again, "No, it's not because of his claws. I trust the lion will not hurt me. The reason he's in the cage is because I'm afraid that if I were to let him out, he'd see how wonderful it is to be free, and he would leave me. I couldn't stand that."

The hyena said, "Oh, but you're wrong, young prince! We love our cages. We'd never leave. Open my cage and I'll show you." The innocent young prince opened the cage and the hyena immediately jumped on the prince to eat him.

Suddenly, the lion jumped out of his cage and grabbed the hyena in his powerful claws. The hyena escaped and ran off, never to be seen again. 

The young prince was surprised and asked, "Lion, how did you get out?" The lion replied, "My prince, my cage was never locked. I have always stayed here because we are friends."

From that day on, the lion's cage door was taken off.
