Answer:
The protagonist wants us to learn how her family's past impacted their views, and the deep connection that she feels with her mother. This is obvious when the protagonists says that her mother tried to make her feel better after her fight with her father. Her mother was very supportive!!
Also, the protagonist's main purpose is to express herself as an American, due to the fact that she now lives in the United States. We learn that she is very happy to be able to express herself properly in this way when she says: "When I was done, I read over my words, and my eyes filled. I finally sounded like myself in English!"
Hope this helps!!
