Final answer:
The narrative is in the third-person limited point of view, focusing on Brian's internal perspective and reactions while describing observable actions of other characters.
Step-by-step explanation:
The passage provided is written in the third-person limited point of view. This point of view allows the narrator to share the internal thoughts and feelings of one character, while describing the actions and spoken words of other characters. In this case, the focus is primarily on Brian's thoughts and reactions to Rufus's teasing. We do not get insight into what Rufus is thinking, only what is observable about him. This creates a more intimate understanding of Brian's experience without fully entering into an omniscient narrative style.
