Why does Chiron avoid some of Percy jacksons questions?

Chiron avoids some of Percy Jackson's questions to maintain a sense of mystery and protect important truths about the world of demigods and their destinies. As a wise centaur and mentor, he understands that certain knowledge could burden Percy or lead him to make hasty decisions. Additionally, Chiron often prioritizes teaching valuable lessons over providing direct answers, encouraging Percy to discover truths on his own. This approach helps foster growth and resilience in Percy as a hero.
