In Book Two why didn't Eurycleia want Telemachus to leave?

Eurycleia is also thinking about Odysseus at this point.
She thinks of Telemachus, whom she helped raise from infancy, as a young Odysseus, whom
she also cared for as a child. Their lives are parallel to her. So, when Telemachus
raises the idea of going off to sea to search for his father, Eurycleia can't help but
think about what happened when Odysseus went off to sea twenty years ago... he never
came back. She is afraid that the same thing will happen to her precious little
Telemachus, that he too will never come back to Ithaca. She believes that Odysseus is
long dead at this point, which makes her really sad, so she doesn't want the same fate
to befall Odysseus's son. Even though she thinks he will never come back, she is still
extremely loyal to him. This means she cares a lot about Telemachus too, and want to
protect him from anything that might happen out at sea. She is also afraid that if
Telemachus does come back, the suitors will be so angry that he left, that they will
harm him or kill him.
