Learn all the ins and outs needed for travel in France and reading and speaking French

I have the "Magistère" fromthe Sorbonne rec'd in 1974
I was married toa French national for 50 years; I am a widower and retired French teacher.
I currently reside in "L Corrèze" a region in South CentralFrance about three hours east of Bordeaux.
I speak French with a 99% Native accent, but ever so light trace of a foreign accent, often not even detected. It's as if I had been reared in France as I think and dream in French, almost always. I also speak Spanish, but it is not at exactly the same level as my French.I speak American English but am very much inthe know concerning British and American differences in usage as I once spent considerable time in Great Yarmouth. I am not young; I have been retired since 2010.
