Final answer:
Brandon does not understand the nonverbal communication Shannon is sending, which involves the use of gestures, facial expressions, and movements that convey messages without spoken words, often based on cultural norms.
Step-by-step explanation:
Brandon does not understand the nonverbal communication Shannon is sending. Nonverbal cues include gestures, facial expressions, and body movements, all of which are critical in conveying messages without words. Our interactions are often guided by a set of cultural norms that dictate how we interpret these signals.
An example is when a person wishes to end a conversation or indicate disinterest, they may avoid eye contact or move away, communicating a message without saying anything directly. It seems in this instance, Shannon's movement away might have been a cue for Brandon, possibly indicating she needed space or was otherwise engaged in thought and not open to follow-up conversation at that moment.
