|Almost more than he can hold|
My kids are the same. My daughters grab as many YA novels and biographies as they can find. My son never really wants to go to the library, but his eyes light up when he sits among the stacks of brightly colored picture books...and then he wants to bring them all home.
I wonder what it would have been like to visit the Great Library of Alexandria, Egypt....I think papyrus scrolls were lighter than books.
