The Destination of a Story

(After attempting to login for the past 25 minutes, i'm finally writing this!!)
We were talking about the destination of a story & how the beginning of some books has hints as to what happens at the end of the book & we looked at the 1st chapter of Pride & Predudice by Jane Austen.
We talked about how there was no description in the 1st chapter until the last paragraph, which showed how Austen wanted the reader to focus on the conversation between the two characters (Mr & Mrs Bennet), who were talking about Mr Bingley moving into town & Mrs Bennet wanting to marry one of her daughters off to him, because he has money. This conversation is so important, because you then know this is Mrs Bennets aim throughout the novel & the destination of the novel will have something to do with marriage & money. 
We also spoke about the fact no characters are introduced until the 3rd paragraph. Before that, Austen only mentions theories to do with marriage (no description of characters or places.) Austen does this to show the reader the destination of the story straight from the beginning. This is a very uncommon way to begin a novel.
Also, the first paragraph is one sentence on it's own ('it is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.') Due to this sentence being the first in the book & in a paragraph on it's own shows that it must have some significance to the story (and it does, the destination is marriage, and the 1st sentence is about rich men wanting a wife.)
