Humankind - as the word implies - is social. We have meetings to attend, appointments to keep, trains and planes to catch or meet. We must attend to business! Hunt and gather, sow in spring, harvest in autumn, work, work, work in factory, farm and office. But how could we be human without the customs and rituals of social life, the ceremonies that mark the turning year, the rites of our passages and the pleasures of our celebrations? Redstone's Social Diary celebrates the days and nights of our human year.
