What a great idea! The trouble I have is that I can never remember quotes unless I have it written down on a piece of paper to read so I couldn't be as good as you and drop them into conversation. I will go find a good quote and come back and edit this post:)
Later... OK I did cheat slightly it is not from a book I have read but I think it sums up the never ending problem we have- but without the beards for us girls!
Books to the ceiling,
Books to the sky,
My pile of books is a mile high.
How I love them! How I need them!
I'll have a long beard by the time I read them. Arnold Lobel
