What does Telemachus keep from his mother Penelope?

Telemachus keeps the news of his journey and the fate of his father, Odysseus, from his mother Penelope. He does this to protect her from further grief and uncertainty, as she is already distressed over Odysseus's long absence. By not revealing his plans to seek information about Odysseus, he hopes to shield her from the painful reality of their situation. This decision highlights Telemachus's growth and maturity as he navigates his responsibilities as a son.
