I think chapter 15 was most engaging because of the scene towards the end that involves the man and two boys. In this scene it shows just how bad poverty was. Dealing with the man wanting to buy bread at a cheaper price and the kids thinking how nice it would be to have some candy. The man is ashamed that his boys have to go through poverty.
The man took off his dark, stained hat and stood with a curious humility in front of the screen. "Could you see your way to sell us a loaf of bread, ma'am?" Mae said, "This ain't a grocery store. We got bread to make san'widges." "I know ma'am." His humility was insistent. "We need bread and there ain't nothin' for quite a piece, they say."
