Some books change our lives. "The book is a gear (...) it won't let you go until it gives your mind a way"., said Victor Hugo. Human relationships involve too many social, moral, ideological to ignore them and make the most of them.
The metro Saint-Michel, where I sing, has given me the opportunity (and continues to do so) to experience amazing, exciting things and to learn every day. It is my field of observation and study, if I may so. This testimony spans a decade (2007-2017) that I find interesting and worth sharing.
With this book, I would like to meet metro users. I want to touch hearts, give an example and show that the metro is not just about transportation.
