This was their way of honoring the dead. The story over, the demands of their own hard, rough lives began to re-assert themselves in their hearts, in their nerves, their blood and appetites. Would that the dead were not dead! But there is grass that must be eaten, pellets that must be chewed, hraka that must be passed, holes that must be dug, sleep that must be slept. Odysseus brings not one man to shore with him. Yet he sleeps sound beside Calypso and when he wakes thinks only of Penelope.
Much of human behavior can be explained by watching the wild beasts around us. They are constantly teaching us things about ourselves and the way of the universe, but most people are too blind to watch and listen.
