While Owen and Miles talk sports, I people watch. And this is what I see: teenagers trying to act like adults. Or how they think adults act. But mostly they look ridiculous, and I wonder what they don't want to do something that's more fun than drinking, smoking, flirting, and making out. Why are those activities considered to be fun?
The narrator observes Owen and Miles engaging in conversations about sports while she focuses on the people around them. She notices teenagers attempting to mimic adult behaviors and finds their efforts quite amusing. Their attempts at appearing more mature seem misguided to her.
This leads her to question the choices these teens make, particularly why they find drinking, smoking, flirting, and making out to be enjoyable. The narrator wonders about the reasons behind their pursuit of these activities instead of seeking more fulfilling forms of fun.
