What did Margie write in her diary?

Margie wrote on 17 May 2157: "Today Tommy found a real book"

• In the story's futuristic world, children learn through mechanical teachers (computers).
• Tommy discovered an actual paper book with yellowing pages something neither child had ever seen.
• They read about old schools with human teachers teaching groups of children together.
• Margie, who hates her mechanical teacher, begins imagining how fun that must have been.

The story is a gentle, nostalgic reflection on the value of human connection in education.

Summary: Margie's diary entry about finding a real book leads her to discover old-style schools with human teachers, making her yearn for that lost community and joy of learning.
