Read the excerpt from The Odyssey.

But when he knew he heard
Odysseus' voice nearby, he did his best
to wag his tail, nose down, with flattened ears,
having no strength to move nearer his master.
And the man looked away,
wiping a salt tear from his cheek: but he
hid this from Eumaeus.

Which theme do these lines support?

Loyalty and fidelity are precious traits.
Overconfidence can lead one to danger.
Making snap judgments is often very unwise.
Love and family make a homecoming worthwhile.
