One of My Students Walked Away in a Call

“We predominantly use Teams for our video calls, and it’ll show you who is in a meeting and how long it is going for. At the end of the class, I will always say, “if you know what needs to be done, you’re welcome to leave the call. If not, hang around, and I’ll answer your questions.” All the students leave except one. I ask him how he’s doing, and he doesn’t reply. I ask again; still no reply. So I left the call and timed how long he was still in there. The kid was still in the call for another 45 minutes before he came back and realized everyone was gone. He still sent me a message asking what they needed to do.”
