On Sunday morning, Alicia rolled her bike out of the garage. She was going to ride to the park with her cousin Mario. But when she sat on the seat, the back tire went flat.

Alicia groaned. Mario would be at the park soon, and she did not know how to fix a tire.

Her neighbor, Mr. Patel, was watering his roses. “I can show you how to fix that,” he said. He found a tiny nail stuck in the tire and pulled it out. Then he helped Alicia cover the hole with a small rubber patch.

Alicia used a pump to refill the tire with air until it was hard again. She squeezed it to check. “It’s fixed!” she said.

Mr. Patel smiled. “Now you know how to do it yourself.” Alicia thanked him and rode off to the park.
