Margie is a little girl of eleven years and Tommy is thirteen-year-old.

Margie wrote in her diary, “Today, Tommy found a real book!”.

 No, Margie had never seen a book before.

Margie was surprised when she heard that centuries ago the words printed on a book stood still instead of moving the way on a screen. She found it strange that the words on a page always remained the same as the first time they were read. Besides, the idea that someone would write a book about schools was itself strange for Margie.
