Part Time Indian.. "Wierd Friendship"

In the book I'm reading "The Diary Of A Part Timer Indian" the main character is this boy who was born with numerous birth issue's , although he is still able to walk, talk , and read he still looks different than a lot of the other kids. But he has this friend named Rowdy and Rowdy is like the neighborhood bully,I mean he is a tough kid strong and built, but there's only one person that he doesn't mess with he not only doesn't mess with him but he is like best friends with him and that person happens to be Junior the main character who all the other kids pick on and bully due to him looking different from everyone else. You would think that the neighborhood all time bully would pick on the kid that looks the weirdest but not Rowdy.But Junior is very luck to have Rowdy around to protect him from the other not so big bullies.
