Once upon a time, in a little house, there was a lonely cat named Kitty. Kitty had no friends to play with on Sunday. She would sit by the window and watch the birds outside. One Sunday, Kitty saw a little bird outside her window. "Hi, bird!" said Kitty. "Will you be my friend?" The bird looked at Kitty and said, "I will be your friend, but you must cover my nest with leaves to keep my eggs warm." Kitty wanted to help the bird, but she didn't know how to cover the nest. She tried to pick up leaves with her paws, but they were too big and heavy. Kitty felt sad because she couldn't help her new friend. Just then, a friendly dog named Buddy walked by. Kitty asked Buddy, "Can you help me cover the bird's nest with leaves?" Buddy wagged his tail and said, "Of course, Kitty! I will help you!" Together, they worked to cover the nest with leaves. The bird was very happy, and Kitty was no longer lonely on Sundays. Kitty, Buddy, and the bird became best friends, and they played together every Sunday from that day on.
