After many under fifteen team members missed the bus, Luma decides to simply watch game instead of coaching the boys. Why did she make this decision? Was she being reasonable?

This question calls for your opinion, there is no right or wrong answer. In my opinion, Luma's decision is completely justified. She has rules for her players, and each and every member of the team is expected to follow those rules without exemption. The players were well aware of what time they were to board the bus. They broke the rules. Had she not followed through, she would have set a precedent that the rules and the team didn't come first.
