There is usually no class since Friday afternoon. Only some majors have classes on Friday afternoon. Maybe your son has his own things to do. Don't worry too much if you are poor. He will take care of himself when he grows up. And now children should be given more time to develop themselves, and they can't stay with their parents all the time. I'm just an outsider, please forgive me if I say anything inappropriate! If teachers are hired from outside, it is possible to attend classes. As students, the more you push us, the more we want to resist. In fact, when we grow up, we all learn to arrange our own time. I hope everyone will encourage me more. In fact, as long as you trust and praise, we will be very happy and will work hard. Hehe, I hope it helps you.
