One reason why Cherry offers explanations to the fundamental challenges within both groups is because she has sincere feelings towards Ponyboy. She sees him and recognizes that she can try to serve as a bridge between both worlds. She seeks to explain why things are the way they are between both worlds in the recognition that Ponyboy is authentic and sincere: "You greasers have a different set of values. You're more emotional. We're sophisticated—cool to the point of not feeling anything ... Rat race is a perfect name for [our life]." In a way, Cherry seeks to explain the differences in order to ease her own conscience.
While being able to articulate the differences between both, she does little else to actually change such a situation. Cherry's offering of explanations is a way to give voice to the situation that exists between both sets of social groups. She does not do much to change it, but she feels that some part of her conscience is eased in how she articulates the realities of both worlds and why they will never be eased.
