Free time is a good chance for teenagers to have fun. What about free time with parents around? Some teenagers want free play without parents’ supervision(监管) while parents and experts(专家) may think differently.
Lin Tao, a middle school student, thinks teenagers should be free to play. “Last time I played with my parents around, I was nervous and just couldn’t enjoy myself to the fullest,” Lin says. “And my friend Chen Xiaoxin has similar experiences. Once, he went out to play with his classmates. Everyone felt uncomfortable with his mother’s supervision.”
Wang Min, a mother of a 14-year-old boy, thinks playtime needs supervision. She explains, “People usually say I like to control my kid, but that’s not true.

He might even get indulged in the stories and can’t get back to real life.
Mr. Ma, a doctor of social studies, says it’s understandable for teenagers to wish for freedom. Free play helps them to be independent. Parents can give them more space.
