We stood in front of the Greek Parliament and watched the changing of the guard, which occurs 24/7/365. The letters etched on the wall behind the guards was all Greek to me. Evzones (the presidential soldiers) perform the Changing of the Guard Ceremony at the Tomb of the Unknown Soldier in Syntagma Square in Athens. The guards must stand perfectly still for one hour three times in a 48-hour period. It takes an extraordinary amount of discipline. I have decided not to apply for the position.
