Now I would like to present you some facts, which show this special friendship between Spider and Jamie.
The reader gets to know, that both know eachother for really long time, because they are neighbours and Spider lives in the house next to Jamie.
Jamie knows, that he can always count on him, when he has got some problems or just when we needs someone to talk to.
So this quotation shows, how happy Jamie is, when he meets his friend: "After supper, he took the basketball, wandered out to the garden and threw the ball up at the basket on the wall, He often found it relaxing to come out here and throw a basketball and there was always the chance that the sound would bring Spider out from next door and they could talk."
So Jamie really whises to see Spider, to have the chance to talk to him.
It's also clear, that Spider trusts him a lot, because when Jamie asks him for the money, to pay the men off, Spider doesn't know, why he wants to have the money but although, he gives it to him because he wants to help his friend, no matter in what situation he is at this moment.
I think, Jamie is really happy to have a friend like Spider, especially, when he flees from his father.
