Justify the title 'The Fun They Had'

The prose 'The Fun They Had' written by Isaac Asimov mentions the schools that may exist in future. And in such an era, the students will only think about the fun that the students have in the current times. The same happens with Margie. She is born and raised in an era that is technologically much developed and advanced and has never been to a school where the students, the teachers gathered, they learned together, ate together, interacted with each other, played together, where children made friends, at times friends for life. It is actually fun to help each other in learning. But as she has not been to such an era, she can only imagine how the students, the teachers, even the parents had fun. Hence, the title 'The Fun They Had' has been appropriately used.
