The three girls were in school. They promised each other to go to one of their houses and play with a skipping rope. The blue one did not want to play with it because she wanted to play hide and seek. They said “But you promised”. It has a story too. “What is happiness?” Happiness means play, fun, whatever on the earth. For instance, the children below are playing with the skipping rope. These are the games that they like. Being happy makes people beautiful. Even though she does not want to, the blue girl is playing with the skipping rope because she promised her friends. She knew that if she did not keep the promise that she gave th her friends would get hurt.
