Thanks for your advices. As tour guide, we work a lot during the summer. I try to always give the same quality of tour, but sometimes I'm a little more tire and my thoughts come by a little bit slowly. My stories cover the red light era from the 20s to the 40s, I try to go by in chronological order. I also divided the tour in different theme. The theme are depended on the location we are. No, its not all linear and it can't be. I take a stand in favor or sex workers right in my tours. I forbids to all the guides who work with me on this tour to use any other terms do describe them. I do not intent to use girls and sex workers as interchangeable. Sex workers are people. It just happen that the vast majority of them are and were girls. As many scholar that I know who studies sex work (in French), I prefer use the feminine to describe their realities.
