Final answer:
The excerpt from The Great Gatsby conveys the theme that people resist changing their feelings about a person after their first impression.
Step-by-step explanation:
The theme that this excerpt from The Great Gatsby best conveys is the idea that most people resist changing their feelings about a person after their first impression. The narrator initially had a positive impression of the person he is talking about, but as he got to know him better and realized that he had little to say, his initial impression faded. This implies that people tend to hold onto their initial judgments of others, even when that judgment may not be accurate.
