How much day is remaining?

It seems increasingly likely that I really will undertake the expedition that has
been preoccupying my imagination now for some days. An expedition, I should
say, which I will undertake alone, in the comfort of Mr Farraday's Ford; an
expedition which, as I foresee it, will take me through much of the finest
countryside of England to the West Country, and may keep me away from
Darlington Hall for as much as five or six days. The idea of such a journey came
about, I should point out, from a most kind suggestion put to me by Mr Farraday
himself one afternoon almost a fortnight ago, when I had been dusting the portraits
in the library.

(Ishiguro pg 3)
  Through inspection of the opening passage of the novel The Remains of the Day, by Kazuo Ishiguro, one can learn much, specifically regarding the personality of the main character, Stevens, as well as the major theme- discovery. The repeated use of adverbs and interjections shows the diffident and submissive nature of Stevens: increasingly, i should say, as i foresee it, etc. All of these choices regarding diction modify the meanings of the sentences: It decreases the confidence and assurance of the narrator- thus this doubt that is created within the first few sentences exemplifies Steven's role as a diffident narrator, who either is not reliable, or merely believes he is not reliable. This perfectly reflects the profession Stevens has chosen- being a butler. A butler, or more so, Stevens the butler, always agrees with his master, whether or not it opposes his personal beliefs. This passage also implies that the rest of the novel will revolve around the voyage that Stevens will supposedly take, and that said voyage will be a journey of self-discovery, as noted by, "which I will undertake alone". Additionally, Stevens, who can be assumed to be a very dependent person, merely on the basis of his profession, can also be assumed to be shocked by the lack of a master. Thus, a close reading of these premiere lines can reveal both the characterization of the protagonist as well as the possible plot.
