I Greci vivono in una sorta di sospensione, non sanno cosa sta per accadere e la vita di tutti i giorni è più difficile che mai. Lo scenario che si sta per aprire il giorno dopo il referendum pro e contro la Comunità europea è sicuramente quello di un paese diviso in due e al dissesto economico si sommerà il conflitto sociale. Greek people living in a sort of suspension doesn't know what is going to happen and ordinary life is getting more difficult than ever. The scenario which is going to open the day after the referendum pro and against European Community is definitly of a Country devided in two which means social conflict plus economic instabilty.
