What are some of the reasons annabeth gives for any Poseidon and Athena don't get along?

Annabeth explains that Poseidon and Athena have a long-standing rivalry rooted in their conflicting values and personalities. Poseidon, the god of the sea, represents chaos and unpredictability, while Athena embodies wisdom and strategic warfare. Their competition for the patronage of cities, particularly Athens, exacerbates their animosity, as Athena won by offering the olive tree, symbolizing peace and prosperity, while Poseidon offered a saltwater spring, reflecting their differing priorities. This clash of ideals contributes to the ongoing tension between the two deities.
