1) The story is set in the year 2157 when books and schools may no longer exist as they do today. Tommy finds an old paper book from centuries ago and is surprised that the words do not change like they do on screens.
2) Margie is frustrated with her mechanical home teacher that keeps failing her on geography tests. A county inspector fixes the issue with the teacher.
3) Tommy tells Margie about old-fashioned schools from over 100 years ago where children went to a special building to be taught by a human teacher alongside other children their age. Margie finds this idea of school more fun than her solitary home lessons.
