Explain the last sentence in the story

This final quote speaks to the propensity of teenage girls to ignore the people around them and see no further than themselves. Girls and boys of this age tend to focus on themselves, pretend they're something they aren't, indugle in fantasy and make-believe, and as a result over think their own importance. It's all about competition and being the best, rather than simply being human. Raymond's presence in the race changed the game and illustrates the human touch.... the reality.
