What is Mr. Nilsons life like? What is his social class?

Mr. Nilson is described as 'well known in the City "-the financial center of London-and though he right away notices the spring morning, he prefers to contemplate the price of Tintos-stock shares. While looking in an ivory-backed mirror, he is described physically as exhibiting "a reassuring appearance of good health,"' despite the aching feeling beneath his fifth rib. His life is rigid and ordered, a fact that can be deduced from the striking of the cuckoo clock that tells him he has exactly a half-hour to breakfast. When he goes out to the square to enjoy the morning, he walks around the circular path two times. He marvels at the blooming quince tree but is also quite concerned about the sensation of "some sweetish liquor m course within him." This illness suggests a disparity between the appearance of Mr. Nilson's life-the way it looks from the outside-and the reality of his inner life.
