If a four-year-old girl is sold to brothel and raised by them with other same age kids in the brothel, she does not have a question on her life. She feels joy when she is praised. She is happy when she gets a chocolate bar as a treat. She is raised as a prositute in the highly limited environment. Her smile is not fake. It is real as same as a usual kid's smile who gets a new toy as a birthday present from the parents.
