A note about Fr and En:
My English writing is entitled a special way in the universities’ catalogues: ‘English as a second language’. This means that I, we, have a first language? Well, some may have many languages and you may not guess which one is the first, the second or the next. I thought that the first language of the human being was love ? Mistake. The first language of the 21st century is a global mix of everything on the web. Not quite pure, but we try our best.
