One day, a boy named Tim went for a walk with his dog, Max. They walked to the park where they saw a big fog. Tim could not see very well, but he could hear Max barking. He called out, "Max, where are you?"
Max barked again, and Tim followed the sound. He found Max near a big empty box. Tim asked Max, "What is in the box?" Max did not mention anything, but he kept barking at the box.
Tim opened the box, and a big bunch of balloons flew out! The balloons lifted the fog, and Tim could see again. Tim and Max were so happy, they played in the park all day.
