They wear white and say it is the colour of peace and hope for the future. You have come to know white as the colour of death. They - the Guardians - keep order with an iron fist and any display of deviation from the norms (emotionless, passive, thoughtless existence) is punished the most severe way possible. So when the man dressed in black walks in, weaving with ease through the tide of white-clad students, you hang back instead of filing out of the hall with everyone else. Who is this man? How has he been permitted to wear clothes which are such an obvious denial of the government? He catches your eye and smiles.
