Margie and Tommy are characters from Isaac Asimov's short story, "The Fun They Had."

Margie is eleven years old, and Tommy is thirteen years old.

They live in a futuristic world where children learn individually from mechanical teachers at home, rather than in traditional school buildings with human teachers. When Tommy discovers an old, physical book, they become fascinated by the concept of schools from centuries past, where children went to a special building and were taught by people. Margie, in particular, finds her mechanical teacher quite boring and dislikes her arithmetic lessons.
