Why does Athena go to Telemachus in disguise?

In disguise as an old friend of Odysseus', Athena travels to his manor in Ithaca, now overrun with noisy, lustful suitors intent on marrying Odysseus' wife, Penelope. Odysseus' son, Telemachus, unhappy among the suitors, greets Athena warmly as a stranger and invites her to their feast. Athena instructs him to call an assembly of the islanders and order the suitors away; then he must sail away to find news of his father at Pylos and Sparta. After this, he must kill the suitors, as Orestes did. Inspired, Telemachus thanks her for her advice, and she leaves.
