In the excerpt from Anna and the French Kiss by Stephanie Perkins, the narrator reflects on their understanding of body language, specifically gestures like Pinkie, which signifies excitement or happiness, and thumb, indicating thinking or worry. The narrator seems surprised to realize they know what these gestures mean, suggesting a moment of self-awareness or curiosity about their own attentiveness.
The narrator questions how closely they've been observing someone, possibly a character in the story, and whether their awareness of these small cues reveals their level of engagement or emotional connection. This introspective moment highlights the importance of non-verbal communication in understanding others' feelings.
