Once upon a time, a big red ball was on vacation. The ball was very attractive. It had a big smile and shiny eyes. The ball liked to give hugs to everyone it met.
One day, the big red ball met a small blue ball. The small blue ball said, "Hi! I like your smile. Can you give me a hug?" The big red ball smiled and gave the small blue ball a big hug.
Just then, something unexpected happened. The small blue ball grew bigger and turned into a big green ball! The big green ball said, "Thank you for the hug. Now I am big and happy too!" The big red ball and the big green ball became best friends and had a great vacation together.
