I’m British and have been living and teaching English in France since 1981.
I’m retired but still teach at home and I also offer “home study language courses” here in my country home in the south-west of France as well as lessons by SKYPE. Details and fees here: http://efl-fle-chezvous.monsite-orange.fr/
