Could you please tell me the precise meaning "busy" and "tired" in the following phrase extracted from the chapter 4 from The Great Gatsby by F. Scott Fitzgerald?
It was dark now and as we dipped under a little bridge I put my arm around Jordan’s golden shoulder and drew her toward me and asked her to dinner. Suddenly I wasn’t thinking of Daisy and Gatsby any more but of this clean, hard, limited person, who dealt in universal scepticism and who leaned back jauntily just within the circle of my arm. A phrase began to beat in my ears with a sort of heady excitement: “There are only the pursued, the pursuing, the busy and the tired.”
Does "busy" refer to characters like Tom, Jordan, frantically busied with social functions, activities, and "tired" those who are disillusioned, detached, like Nick?
