Why did Thetis wait 12 days to make an appeal to jove?

Thetis waited 12 days to appeal to Jove (Jupiter) after her son Achilles withdrew from battle due to Agamemnon's insult, as she needed time to consider the best course of action. During this period, she witnessed the dire consequences of Achilles' absence from the fight, prompting her to seek divine intervention. Additionally, the delay allowed her to reflect on the gravity of the situation and the importance of her son's honor in the conflict. Ultimately, she sought to ensure that Achilles would be restored to glory and vengeance against Agamemnon.
