One day, a little girl named Lily went to the park to play. She saw a perfect tree with big branches. Lily thought it would be fun to climb the tree. She started to climb up, up, up.
As she climbed, she found a big sheet stuck in the tree. She tried to pull it down, but it was stuck very tight. "Oh no!" Lily said. "I need help!" A boy named Tim heard her and came over to help. He climbed the tree too, and together they pulled and pulled on the sheet.
Suddenly, the sheet came loose, and Lily and Tim started to fall. They held onto the sheet, and it acted like a parachute. They floated safely down to the ground. They laughed and smiled, happy that they had worked together to solve the problem.
