An attempt to understand the lives of those who live and work in Brussels, as simply as possible.  If these streets are full of life, the most obvious activity in the area is without doubt the sex industry.  Some endorse it without hesitating.  Others reluctantly accept it, do not understand it or cannot accept it.  Prostitution sparks debates yet it is a fact and those who work in the field exist.  Sometimes they are willing, at other times reluctant.  They are at the heart of the question.
