How does paragraph 6 mainly add to the development of Mr. White ?

From the text, we can infer that Mr. White is frustrated with his life.

“That’s the worst of living so far out,” cried Mr. White with sudden and unexpected violence; “Of all the awful out of the way places to live in, this is the worst. Can’t walk on the footpath without getting stuck in the mud, and the road’s a river. I don’t know what the people are thinking about. I suppose they think it doesn’t matter because only two houses in the road have people in them.”
