(…) Margie went to the schoolroom. It was right next to her bedroom, and the mechanical teacher was on and waiting for her. It was always on at the same time every day except for Saturday and Sunday, because her mother said little girls learned better if they learned at regular hours. The screen was lit up, and it said: Today’s arithmetical lesson is on the addition of proper fractions. Please insert yesterday’s homework in the proper slot. Margie did so with a sigh. She was thinking about the old schools they had when her grandfather’s grandfather was a boy. All the kids from the whole neighborhood came, laughing and shouting in the school yard, sitting together in the schoolroom, going home together at the end of the day. They learned the same things so they could help one another on the homework and talk about it. And the teachers were people… The mechanical teacher was flashing on the screen. When we add the fractions ½ and ¼ … Margie was thinking about how the kids must have loved it in the old days. She was thinking about the fun they had.
