Once upon a time, there was a little boy named Tim. Tim was sad and gloomy one day. He didn't want to play with his toys. His mom asked, "Why are you so gloomy, Tim?"
Tim said, "I want to make a big sand castle, but I don't have any sand." His mom had an idea to make Tim happy again. She said, "Let's go to the park and carry sand to make your sand castle!"
Tim and his mom went to the park. They found a big sand box. Tim and his mom started to carry sand in their buckets. They carried and carried sand until they had a big pile.
Together, they built a big sand castle. Tim was not gloomy anymore. He was very happy. Tim and his mom played with the sand castle all day.
