The Greeks believe the Fates are three sisters: one is Order, who spins out the linear thread of a life from the beginning; another is Irony, who gently cocks up the thread, marking it with some peculiar sense of balance, like justice, only blind drunk with a scale that's been bunged into the street so it never quite settles; and the third, Inevitability, simply sits in the corner taking notes and criticizing the other two for being shameless slags until she cuts life's thread, leaving everyone miffed at the timing.
