Odysseus boasting of blinding Cyclops and Cyclops seeking revenge

Explanation:

In the Odyssey, Odyssues foolishly blinded the cyclops Polyphemus who was the son of the chief god Poseidon. He then taunted Polyphemus as he left and in his boast even revealed his name .

The Cyclops then sought revenge and cried to Poseidon for revenge and Poseidon intervened and made Odysseus's journey home so hard and tumultuous and at some point even destroyed his ship.

Had Odysseus abstained from the boast and avoided mentioning his name, Polyphemus might not have sought revenge or at least would not have known who he was which would have allowed Odysseus avoid the unwanted consequence of angering Poseidon.
