Question

what did the margie's grandfather tell her

Answer 1

This question seems to be completely irrelevant.

You cannot ask such a question without giving reference.

You need to tell the name of the story.

Once you tell the name of the text then only one can read the story and see it.

Otherwise only if somebody has read the story and it clicks in his mind can answer it.

Answer 2

Answer :

In the short story 'The Fun They Had' by Isaac Asimov, Margie's grandfather had once told her that when he was a little boy his grandfather had told him that there was a time when all the stories were printed on paper.

The following lines from the story provide the answer :

'“Today Tommy found a real book!”  It was a very old book. Margie’s grandfather once said that when he was a little boy his grandfather told him that there was a time when all stories were printed on paper.'
