Leslie's traits change throughout the book because she is less brave after she admits that she doesn't have a TV because the girls in her class pick on her for it.
This is Jesse Aarons. He is the narrator and Protagonist of this story. Leslie Burke is his neighbor.
Jesse Aarons is determined. In this passage Jesse wakes up early to practice running. "Where you going, Jess?" May Belle lifted herself up sleepily from the double bed where she and Joyce Ann slept."Sh." He warned. The walls were thin. Momma would be mad as flies in a fruit jar if they woke her up this time of day. He patted May Belle's hair and yanked the twisted sheet up to her small chin. "Just over the cow field," he whispered. May Belle smiled and snuggled down under the sheet. "Gonna run?" "Maybe." Of course he was going to run. He had gotten up early every day all summer to run. He figured if he worked at it- and Lord, had he worked-he could be the fastest runner in the fifth grade when school opened up. He had to be the fastest- not one of the fastest or next to the fastest, but the fastest. The very best. This passage represents how he is determined because he wakes up early every day to run, so that he can be the fastest.
Jesse Aarons is artistic. In this passage Jesse is in his room alone and can finally do what he loves to do; draw. "He closed the screen door gently as he entered and slipped past his mother, who was rocking herself in the kitchen chair watching TV. In the room he shared with the little ones, he dug under his mattress and pulled out his pad and pencils. Then, stomach down on the bed, he began to draw. Jess drew the way some people drink whiskey. The peace would start at the top of his muddled brain and sleep down through his tired and tensed up body. Lord, he loved to draw.". This passage represents how Jesse is artistic because drawing brings him peace in his very bust and hectic life.
Jesse is giving. In this passage Jesse is giving Leslie her Christmas present. "At the stronghold he tied the ribbon around the puppy's neck, laughing as it backed out of the loop and chewed at the ends of the ribbon. It was a clever, lively little thing- a present Jess could be proud of. There was no mistaking the delight in Leslie's eyes. She dropped to her knees on the cold ground, picked the puppy up, and held it close to her face.". This passage represents how Jesse is giving because he gave Leslie a thoughtful gift, that he knew she would like.
Jesse's traits change throughout the book because he is less giving of his time whenever Leslie wants to hang out with him but instead he goes and hangs out with his teacher at a museum. If he would've invited Leslie instead of his teacher the story would probably have a whole different meaning.
