What are the motifs in Boule de Suif by Guy de Maupassant?

Social order and scandal are recurring ideas. Maupassant uses the social order to create a hierarchy inside the coach. The entourage is composed of differing social orders: two nuns, a prostitute, a democrat, and respectable, socially elite individuals. The nuns are dedicated to God. Appropriately, they engage in very little regarding scandal or squabble in the social order. The prostitute is a fringe element of the social order, dedicated to hedonism and immoral earnings.
