Historia del NO

"NO" is one of the first words we learn. It's such a short but frequent word that it's certainly useful to know more about it. How did "NO" come about? What is it for? It's known to have been used all over the world for a very long time. Furthermore, not all "NOs" are the same. Some are annoying, others boring, and others sad, but there are also some important ones (history is full of examples: Rosa Parks's "NO" to giving up her seat), others just (NO to war! NO to pollution!), and, on the contrary, others unjust (NO to freedom, NO to equality), some said for a good reason and others not... A book you can't say NO to!
