Why doesn't Brady open up and talk to Carl in the book Red Kayak?

In "Red Kayak" by Priscilla Cummings, Brady struggles to open up to Carl because he feels a heavy burden of guilt and fear regarding the incident that involved the kayak. He is concerned about the repercussions of revealing the truth and how it might affect their friendship and the community. Additionally, Brady is grappling with his own emotions and the weight of responsibility, which makes it difficult for him to share his feelings with anyone, including Carl. This internal conflict ultimately leads to his silence and isolation.
