Once upon a time, in a big green park, there was a little circle. The circle was very happy. It would roll around the park all day long, playing with its friends. The circle had many friends like the square, the triangle, and the star.
One day, the circle was playing with its friends when it saw an angry bird. The bird was mad because it could not find a place to rest. The circle wanted to help the bird, so it rolled over to the bird and said, "Don't be angry, bird. You can rest on me."
The bird was very happy and thanked the circle. It rested on the circle and soon fell asleep. The circle was happy that it could help its new friend. From that day on, the circle and the bird became best friends and played together in the park every day.
