The young man in the blue shirt holds the ladder for the man in the white shirt in a graffiti-covered alley.
A couple of volunteers are using a ladder to help clean up an alleyway that has been vandalized by some local street toughs.
Two men are in the alley with a ladder but that does not indicate that they are volunteers. They aren't necessarily helping to clean up the alley and the alley may or may not have been vandalized by some local street toughs.
