What are the artifacts in Arnold's life on the reservation and off the reservation in The Absolutely True Diary of a Part-Time Indian?

What are the artifacts in Arnold's life on the reservation
and off the reservation in the novel, The Absolutely True Diary of a Part-time
Indian? Thanks to the brilliance of author Sherman Alexie, there are many
artifacts. One starts with the protagonist's name. On the reservation, he is Junior,
like so many other Indian children. In Reardan, he is called Arnold Spirit. As Junior
relates his life to A Tale of Two Cities, the reservation is “the
worst of times” and Reardan is “the best of times.” On the reservation, Junior’s best
friend is Rowdy, whose name reflects his violent tendencies. In Reardan, he managed to
become friends with Gordy, a boy as intelligent as
Arnold.

The two worlds are diametrically opposed. The
reservation is characterized
by:

• Hopelessness.


• Abject
  poverty.


• Alcoholism that often leads to deaths.
  


• Hunger occasionally punctuated by a bucket of Kentucky
  Fried
  Chicken.


• Powwows.


• Poor
  education with school books that belonged to students’
  parents.


• Generous and rare gifts of $5, which usually
  mean a parent has forfeited getting drunk.


• Hitching rides
  or walking to and from school.

Reardan
represents hope, the driving force that leads Junior to make the momentous decision to
leave the reservation to pursue a better education. His white girlfriend, Penelope, has
bulimia, an addiction similar to his father’s alcoholism. Money and cars fly around
freely, while white fathers blend into the background.
