In this excerpt, Nick makes it clear that Gatsby does not seem to be like the other people around him. He picks his words with care, as if he was playing a part. He also seems to be trying too hard, as Nick tells us that his formality of speech "just missed being absurd." It seems like Gatsby is not as sophisticated as everyone else, but he does not want anyone to notice. However, Nick can see through it, developing the theme that Gatsby is an outsider in this luxurious world.
