The only thing that makes me think that she may be a child prostitute, given the area it is shot in, is the earrings and the hollow eyes. Her dress does not look all that gaudy to me ( and btw, her arms look healthy to me, not pudgy). As a matter of fact, take away the earrings, and she just look like a very poor young girl .
I don't know if you have seen some second and third graders in the USA lately but they often dress much more gaudy.
Didn't they ever have a cover about masturbation? How can i over come this or some such nonsense? Poor kids, as if being pre -teen was not a hard enough time.
