What does Carl Luce mean by a typical Caulfield conversation?

In J D Salinger's novel 'The Catcher in the Rye', Carl Luce refers to a 'typical Caulfield' conversation' in the context of Holden's interaction with his former English teacher, Mr. Antolini. He describes it as a conversation where Holden keeps changing the subject and digressing from the main topic. According to Carl, when Holden wants to talk about something personal or revealing, he starts going off on a tangent, unable to focus on the intended topic of the conversation. Luce observed this pattern when Holden had come to him for advice about his future.
