A commonality I notice with both 10 year olds & college students is that they get up and leave the room for 5 minutes or so constantly. For the little kids, it is ostensibly to go to the bathroom, and they always ask first. For college students, I have no idea, but I suspect it is to check their phones. Why is it young people can't sit still for an hour without needing to pee or wash their hands or send a text?
