     Margie went to her school. It was the next room, a virtual classroom. There was a machine teacher for Margie. It was on, and it was waiting for her to begin teaching her. Margie studied all the weekdays except Saturdays and Sundays. Margie’s mother was very concerned about this as she felt Margie would learn better if she would study every day at the same time.
