Everyday of that summer...
"Every day that summer we went to the pine beside the stream of Old Woman Swamp, and I put him on his feet at least a hundred times each afternoon." The author tries to show the reader the pride Doodle's brother has in him, for he is determined to make Doodle walk just for his own good. He does this by using descriptive words that the reader can picture.
This is all my fault!
"The last graveyard flowers were blooming, and their smell drifted across the cotton field and through every room of our house, speaking softy the names of our dead." The author is creating an image in the readers mind by using descriptive details of his yard, and personification of the flowers.
The style of the story is written as a narrative, where the narrator is telling a story as a flashback. The author uses many details so the reader has a good idea of what is happening. The story is easy to picture and is entertaining to read, with many page turners.
The theme of the story is pride because the narrator focuses on his own selfish pride throughout the whole story. When Doodle died, his brother felt so ashamed of himself and his actions because he didn't want to be embarrassed by Doodle. He realized he could not take back his mistake and that he now had to live with a miserable regret.
