Why "du" (you familliar) is missing from Fluenz course? I m at CD2 L04
In a Top 30 words -spoken in German, "du" is in 7th place see web: http://german.about.com/library/blwfr... When you will speak with a friend, colleague or somebody that you know for some time, you wont use "Sie" because sounds strange. So my question is: why "du" was not introduced from the first stages of Fluenz German? and will it be presented later on?
