They disagree about the role that the "old ways" should play in their lives.
Explanation:
In "Julie of the Wolves" by Jean Craighead George, the story is told of a teenage girl Miyax Kapugen who was adopted by a pack of wolves, her stay in the wild, and her eventual return to civilization.
Flashback is used to relieve her stay with her father in a seal camp and how he teaches her the Eskimo lifestyle. When she goes back to stay with her aunt Martha that she doesn't exactly get along with, the major conflict between them is their disagreement about the role that the "old ways" should play in their lives.
