The Story of Lucy Gault by William Trevor (Pages 46-94)

SUMMARY:
From pages 46-71 was the last pages of part one of the story. It was about how Lucy was found in the woods. She had wounds and cuts on her face that bled down to her mouth that she can taste. Lucy parents already left town because they thought Lucy died so now Lucy is left alone with Henry, a Kilauran boy, one of seven in a fishing family. Lucy also stayed with Bridget that found her, she is Henry's wife. When Lucy was asked if she knew anything about her parents' plan of traveling, she didn't say anything except shake her head.
Part two which starts on page 72, it's been months since Lucy was separated from her parents. Lucy is starting school again, she's learning to read and write, she have to do her work in a used and written all over notebooks/textbooks. One day when Lucy headed out the house, she was almost crashed by this boy named Ralph, because he didn't think anyone would be coming out of that house. Lucy Gault is growing up, and she is looking more beautiful than before. Ralph have been teaching this boy the alphabets, so he stayed for awhile. He started to like Lucy and Lucy liked him back. Ralph was about to leave the place when Lucy wrote him a letter. The letter was Lucy saying she hopes Ralph would stop by for some tea before he leave...if he have time.
QUOTE:
"Lucy Gault was beautiful all that summer. She was beautiful in her plain white dress, the sunlight catching the dots of silver in the stoneless earrings she wore"(Trevor 88).
REACTION:
From today's reading, it showed that Lucy have changed. She literally grew older and more mature. She's going to school, and she started to look like her mother. When she the boy Ralph, she started to like him and he likes her back. The quote above, describes how Lucy is becoming more like her mom which means looking older. The white dress was suppose to be her mother's if she was still here. The dress was left behind which now is Lucy's and they said she looks great in it. Lucy doesn't seem like she miss her parents in any kind of way. Lucy is just living her life even though she doesn't say much in the story.
This book was took from a third person's view which to me, should had been from Lucy's point pf view(first person). Because it is a third person's view, it doesn't show Lucy's emotions and thinking.
Why doesn't Lucy tell Henry or Bridget that she knew her parents plan the trip and she just didn't want to move so she pretended that she was missing? I think if the others knew about it, they would try finding her parents but instead, now they think her parents just left her behind.
Why did the author separated the story into different parts?
Why doesn't the author focus on Lucy's life? Instead he wrote about events that were important to the story.
