THIS MIGHT NOT BE CORRECT THIS JUST MADE THE MOST SENSE TO ME SORRY IF ITS WRONG I APOLOGISE SINCERELY!!
Answer:
I think the answer would be
Zane appreciated his dad’s offer to help, but he wanted to do it himself.
Step-by-step explanation:
I believe it shows that Zane is independent and wants to try to do this by himself because if he can he will feel acomplished and happy/ proud of himself for being able to do it without any help.
This is a lil bit more like me:
Maybe Zane also was like if I can do this great but if I mess it up even more I have no one to be mad at except myself.
This would show that Zane doesnt want to hurt peoples feelings by getting mad at them.
