Budding Librarian?

H is very funny at the moment - she has lots of little quirks and expressions and continues to amaze me every day. Today, all was quiet for a while, and when I found her, she had pulled lots of books from our book shelves and was sorting them into bundles and rows. Then, she lined them all up against the wall/shelf, facing the front. It wasn't quite right obviously, so quite a lot of shuffling of the order of books ensued, and this was the finished product. I am not sure whether the books were chosen at random or there was some method to the madness....
