first a reaction from my side, to avoid confusion <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
If you plan to write something in german, and use the word 'Sie', pay close attention to the capital.
the word sie can be interprented in multiple ways.
without capital : sie -> they
with capital : Sie -> reserved for adults, strangers and people you don't like. (quoting kiya <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> ) (you need to adress people with this)
