One day, a little lion named Leo was playing in the big universe. He loved to roar very loud. He was a careless lion and did not know that his roars were too loud for his friends.
"Please don't roar so loud, Leo!" said his friend, the small bird. "It hurts our ears." But Leo did not listen. He just wanted to roar and have fun.
One day, something unexpected happened. When Leo roared, a big star in the sky heard him. The star came down to talk to Leo. "Your roars are so strong, they shake the whole universe!" said the star. Leo felt bad and promised to be more careful. From that day on, he roared softly and all his friends were happy.
