One day, it is very hot. A bird is standing in the tree. There are many green leaves on the tree. He feels cool in the tree. A cat is hot and hungry. He sees the bird and wants to eat him. He climbs the tree quickly to catch the bird. The bird sees him and flies in the sky. The cat says, “Hello, beautiful bird. I’m your good friend. Come down and play with me.” The bird doesn’t fly down. He says, “Sorry. You can’t fly. You can’t play with me.” Then the bird flies away.
