What is the main conflict in The End of Old Horse by Simon J. Ortiz?

One aspect that is particularly notable about "The End of Old Horse" is the story's lack of a general conflict. There are times when tension is raised, as when the narrator accuses Tony of being negligent and Tony shoves him or when Gilly curses at the family supper table and readers expect trouble to ensue. None of these problems develop into conflict, however: the story cannot be said to be "about" the conflict between Tony and the narrator or Gilly and his parents. Instead, Ortiz uses these tense moments to hold the reader's interest while pursuing a larger, less explicitly defined idea. The story is more about the characters' attitudes than it is about their interactions with each other: if one were intent on defining it in terms of conflict, it would be more accurate to say that it is about a series of internal conflicts.
