I'll tell you all something for nothing: the "exit" of Grexit is not the not the same as the "exit" of Brexit. The former would not have entailed leaving the EU, but leaving the Euro. The Euro is a common currency used in a majority of the member states of the European Union. The European Union is an organisation consisting of a number of states in Europe. Europe is the name given to a region on the western side of the landmass known as Eurasia, which is the largest landmass on a planet known as Earth, which a component of a star system known as the Solar System.
