A holiday is when you celebrate something that's all finished up, that happened a long time ago and now there's nothing left to celebrate but the dead.
Schoolboy days are no happier than the days of afterlife, but we look back upon them regretfully because we have forgotten our punishments at school and how we grieved when our marbles were lost and our kites destroyed – because we have forgotten all the sorrows and privations of the canonized ethic and remember only its orchard robberies, its wooden-sword pageants, and its fishing holidays.
