In a quiet community, there lived a boy named Xiaoyu. He was a top student in his class, but what surprised everyone was—he loved playing games too! Xiaoyu’s parents had a special way of dealing with his gaming. Every day after finishing homework, his mum would say, “You’ve worked hard! 刷速度 返回目录 15 Let’s play your favourite game for 40 minutes. But remember, we need to stop on time.” His dad always kept his promise: when the time was up, he’d gently remind Xiaoyu with a smile, “Buddy, time’s over. Let’s read a book or play basketball now.” Across the street, there was another boy named Haohao. His parents were different.“Stop playing games! You’re just wasting time! Go to study!” his mum would shout. If Haohao tried to argue, his dad would add, “We work hard to raise you. You must study all the time, or you’ll end up like us—no future!” So Haohao often hid in his room, playing games secretly. He felt guilty but couldn’t stop, because games were the only fun in his stressful life. 刷速度 返回目录 Amei, a community volunteer, noticed these two families. One day, she talked to Xiaoyu’s parents.“Your way is amazing! You set rules but also respect his hobbies. Kids need balance between study and fun,” she said.

Let’s play badminton together after that!” Haohao was shocked at first, but soon he felt 刷速度 返回目录 happier. He even started to finish homework faster to earn game time, and his grades improved too!
