The slum was significantly different from the Business and Residential districts. The streets were narrow, filthy, and unattended. Less activity was seen on the street. Some ruffians sat by the side of the street, eyeing anyone that came through, like an owl waiting for a rat to cross by. Raj's attire surely picked their attention.

You could just end up hitting a poor bastard, or sometimes you could even end up being the one that got robbed, so they left Raj alone. As he traveled, Raj was wondering how a sweet girl like Sunshine was safe traveling around such a place.
