After playing joyfully all afternoon, it was finally time to go home. The kids were still a little reluctant to stop, but the thought of continuing their fun at home brought smiles back to their faces. They slung their backpacks over their shoulders and happily ran to meet their waiting parents.
Zhou Fei, however, suddenly lost his smile. He tugged down his pants to cover the scrape on his knee and walked carefully toward his mother, obediently greeting her, "Mom."
Mrs. Zhou glanced down at him, noticing the sweat on his face. "Why are you sweating so much?" she asked suspiciously.
Caught off guard, Zhou Fei panicked for a moment but quickly came up with an excuse. "It's just... really hot," he stammered.
It was only early September, and the weather was still a bit warm, so Mrs. Zhou didn't press the issue. She nodded and began walking him to the car. As they walked, she asked, "What did you do at school today? You didn't play with those other kids, did you?"
