Prudence and loyalty, because in the story, Odysseus is disguised as a very old man, (so he can visit his old home without anyone knowing it's him- many drunk men were at his house to ask for the hand of his wife, since they thought Odysseus would never return, and if they would've found out that his wife's husband has returned, the drunk men would've killed Odysseus), and when he enters his old house, his wife tells their maid, (Penelope), to take care and wash up the old man, which she does, but she finds out that the old man is actually Odysseus! He can't have ANYONE knowing, (as explained before), though Penelope senses that his presence is supposed to keep secret, so she doesn't say a word about it. Penelope's actions gives us an insight of her character traits, known as prudence and loyalty. =) I hope I helped! =D
