In summer, librarians use curtains and blinds more than clouds. This is because there are few things nicer than a cool library when it is hot and bright outside. I like to go to a library and lean my head on the metal shelves when it is very hot outside. Libraries aren't too nice on a hot day because then too many people will come. Librarians are Mothers.
Books are children.
Librarians love their books. They take care of them. Literary critics will say a book is bad or good, but that doesn't matter to a librarian. All books are equal in the sight of a librarian. A book of this kind is often loved even more.
