Greek values woven into this epic poem are often done so as we see the characters violating them. These include hospitality on the part of a host, good manners on the part of the guest, and the heroic ideals of leadership, wisdom, honor and skill in battle. We see this when the suitors at Penelope's home violate these social conventions, taking advantage of the fact that her husband is not home, behaving rudely to their host and other guests, wasting food, and refusing to leave. Not to be outdone in the area of social faux pas, Odysseus breaks the rules of heroism and good manners, making fun of Polyphemus after he defeats him. For this, he earns another ten years away from home at the hands of a disgusted Poseidon.
