Hallo I have issues with the you in German. So you have du, which is for one peron only and familiar. Bist du hier mein freund? Then Sieis for a lot of people. More than one. (All of you are eating is Sie essen) but then what is you when you want to be polite? Is it Sie or Ihr? What is the difference between sie and ihr? If I want to be formal with one person shall I use Ihr or Sie? What about formal with more than one person? I'm lost... Many thanks C.
