Most of the people at that early hour were still in bed and asleep. A few, who intended to go over to the Chênière for mass, were moving about. The lovers, who had laid their plans the night before, were already strolling toward the wharf. The lady in black, with her Sunday prayer-book, velvet and gold-clasped, and her Sunday silver beads, was following them at no great distance. Old Monsieur Farival was up, and was more than half inclined to do anything that suggested itself. He put on his big straw hat, and taking his umbrella from the stand in the hall, followed the lady in black, never overtaking her. —The Awakening,
Kate Chopin
