Haha, here come the conspiracy theorists. I guess no forum is complete without those. No, I don't work for any publisher and don't care about promoting anyone's book. Some of us are busy, darling. Here's the explanation: I am the person who recently read the book (audiobook actually), and have been intensely curious about this matter ever since. The person posting the original question is my assistant. I asked her to go and research the improvement versus cultivation thing, and she found this site. When she updated me on her findings and gave a link to the thread, I found it interesting and decided to chime in myself for some discussion. Mystery solved. Here's a Scooby snack ;) Both the book about French Women and the three "before" movies (Before Sunrise, Sunset, and Midnight) sparked my interest in potentially living in Paris in 2014, so I'm only starting my journey now. I really appreciate everyone chiming in. I did email the author and ask her the same question, but she hasn't gotten back. I will try again, and if she replies I'll definitely post it here.
