One day, a little boy named Tim found a big white box in his room. He did not know where it came from. Tim was very excited to see what was inside the box. He tried to open it, but it was too hard for him. He called his mom and said, "Mom, can you help me open this big white box?"
His mom came into the room and helped Tim open the box. Inside the box, they found a very pretty white dress. Tim was confused because he did not wear dresses. His mom smiled and said, "This must be a surprise for your sister, not for you!"
Later, Tim's sister came home and saw the white dress. She was so happy and put it on right away. She wanted to show her friends her new dress. She ran outside but did not see the water on the floor. She slipped and fell down. Her white dress got dirty. Tim's sister was sad, but Tim gave her a big hug.
In the end, Tim and his sister learned to be careful when they were excited. They also learned that sometimes surprises can be for other people, and that is okay.
