It was lent me, so I read! Already, the title is null by itself. But, one could imagine that the book is, if not exciting, a little interesting! Not even! Honestly, do not waste your time, use not your eyes. There is nothing in this book! However, I am not surprised that Christine Boutin who has ideas for two balls on the subject will be given to this kind of exercise. Intellectual level of this item: zero!
