Interesting how you write "Du" and not "du". I'm French and I've been living in Germany for 20 years. I understand and use "du/Sie" more or less appropriately (we have the same dichotomy in French). What I still cannot wrap my head around after all this time is why/when some people use "du/Du", "dein/Dein", "dich/Dich" in writing (to be clear: not at the beginning of a sentence). I guess "Du" is somewhere inbetween "du" und "Sie" on the politeness scala but I never dared to ask. I'm only using lowercase "du". What would be a rule of thumb on how/when to use the uppercase "Du"?
