Yes you are absolutely right, I think you understand that I wanted just tell you the possibility and not recommend you to force things in that way.

But one thing I want write something:

"We know that Germans tend to keep a proper distance to strangers"

Just cause I really don't like to generalisize I should tell you that in this way you write I disagree - I am also a german and I don't think that I tend to keep a propoer distance to strangers, for me it doesn't matter where somebody come from or what colour have his skin and so on, just what matter is the behaviour and this can be good or bad by strangers as it can be good or bad by germans.
