Zalim, those (techniques) were basically the "love poems" (how you praise your girl, how you express yourself, how you show your love for her). Mario called them metaphores.I can understand Neruda being a mack-daddy.Mario delivers hundreds of(love) letters for Neruda everyday.By the way, Mario was hired as a postman only because there were so many letters everyday for Neruda.So, basically he was Neruda's postman. If you like Il Postino, and want Pablo Neruda's selected love poems read by various actors and actresses (Madonna, Julia Roberts, Andy garcia, Samuel Jackson....etc), you can buy a CD.Besides my love for Italian movies, music, and food, this is one of the best gifts I got from my friend ,Gaurab Tewari, who had grown up in Italy.
