Not me but my son is completely fluent in French and also knows, but is not fluent in, German, Russian, Polish, Slovenian, Norwegian and also has learnt a bit of Latin, Kashubian, Slovincian and old Prussian. He loves language structure, syntax and the roots of languages. I just asked him to list them and he's still rabbiting on about it
