Lila and Tom were playing in the park. They liked to look for things in the grass and the trees. They found some stones, some leaves, and some twigs. Lila picked up a twig and tried to whistle with it. She put it in her mouth and blew hard, but nothing happened.
"Look, Tom, I have a whistle!" she said.
Tom looked at her and laughed. "That is not a whistle, Lila. That is a twig. You cannot whistle with a twig. You need a hole in it, like this." He showed her his whistle, which was a small plastic tube with a hole in the middle.
"Wow, can I try?" Lila asked.
"Sure, here you go." Tom gave her his whistle and took her twig. He blew on the twig, but nothing happened. He smiled and said, "See? It does not work."
Lila put the whistle in her mouth and blew hard. She made a loud sound that scared some birds. She was very happy and said, "Look, Tom, I can whistle!"
Tom clapped and said, "Good job, Lila! You are very smart. Can I have my whistle back?"
Lila nodded and gave him his whistle. They took turns whistling and laughing. They did not see a hidden squirrel that was watching them from a tree. The squirrel was curious and wanted to try the whistle too. It waited until Lila and Tom were busy with something else, and then it jumped down and grabbed the whistle. It ran away with it, making a funny noise.
Lila and Tom heard the noise and looked around. They saw the squirrel with the whistle in its mouth. They were surprised and said, "Hey, that is our whistle! Give it back, squirrel!"
They chased the squirrel, but it was too fast and too clever. It climbed up another tree and hid the whistle in a hole. Lila and Tom could not reach it. They were sad and said, "Oh, no, we lost our whistle. How will we whistle now?"
They looked at each other and had an idea. They put their lips together and blew. They made a sound that was like a whistle, but softer and sweeter. They smiled and said, "Look, Tom, look, Lila, we can whistle with our mouths!"
They whistled with their mouths and forgot about the whistle and the squirrel. They were happy and had fun. The squirrel watched them and felt sorry. It took the whistle out of the hole and dropped it on the ground. It hoped that Lila and Tom would find it and forgive it. It whistled with its mouth and ran away.
