You blinded my son. I will make the sea your enemy. The god of the oceans held a grudge for a decade. Because Odysseus was too proud not to shout his real name after escaping the cave.
Here's the thing about Odysseus: he couldn't help himself. After blinding Polyphemus and sailing safely out of range, he stood at the stern and shouted his real name at the Cyclops. His men begged him to stop. He didn't. Polyphemus prayed to his father Poseidon, and the sea god spent ten years making good on that prayer. One moment of ego. A decade of consequences. Sounds familiar.
