The story is about the year 2157, when every child has his own machine-teacher and schools do not exist anymore. In that year the 13 y.o. Tommy finds an old book. He and Margie, who is eleven, find it strange that the words on paper do not move after having been read. In their time they only read stories on the computer screen. The book they have found is about school, centuries ago. Margie is very surprised that in the past pupils had a real person as a teacher and that all children of the same age learnt the same thing and went to a school together with other children. Margie wants to read more of the book, but first she has to learn with her machine-teacher, whose level is too advanced for her, and she thinks school in those days was much better than today.
