Robert, with all due respect to your experience of so so many years - I don't think that you get my point.
The course sometimes or often mixes different registers like a bad stew with ingredients that don't match together. I'm not worried about anyone frowning over my french, and I want to understand everyday spoken french and barely any native speaker in any language talks like a textbook. I'm not Novak Djokovic and I suppose that the number of world class tennis players giving french interviews with respectful journalists, is very limited. I assume that most every day situations are quite different.
People learn languages in school and courses for years, formal textbook language and understand nothing when they talk to a native speaker… or when they listen to native speakers talking to each other.
I thought this could be an interesting exchange of ideas and means to learn french and that is why I gave you that example - as an input for you and others, but you don't seem to be open for it.
The tutor program that I use in combination with the course has been a great compliment and help to it and certainly for me. Others have looked into it and saw the value of it, as it might not be perfect, but very very helpful.
BTW I lived in New York for a year quite some time ago, after years of series and films in original english version and talking to a friend from NY for years and people didn't think that I'm from Europe, from a country where english is not the first language. Why was that? Cause I had picked up (american) english how it is actually spoken and I didn't talk like I was reciting a textbook. I could understand the fastest and sloppiest New York accent and some other fast spoken american accents as well.
I like to get into the details and nuances of a language and into the cultural differences that come with it as well. Language is much more then words and grammar.
That is my interest weather you personally think that I'm devoting too much energy to the notion of register or not. That is only one part of the nuances of the french language that fascinates me, amongst many others and I will keep devoting as much energy to it as I like. Cherio !
