Where's The Name "Notes For Exchanging" Came From?

It's about the reason why I named the book tittle as "Notes From Exchanging".

This book is named "Notes For Exchanging" is because in the story, Liz and Willelm exchange notes when they can't talk or meet. They pass handwriting little notes to each other during class breaks when they meet on the corridor. Liz keeps all the notes that Willelm has given her. This is kind of old-fashioned way to communicate. Ha!
