Tarp38, what you say is so and is in the culture of all the loosely
Germanic cultures both in German speaking countries and Scandinavian countries .
BUT , the reason is friendship is treated FAR more serious in these lands and holds many more obligations .
As a Finnish friend of mine said, "Americans are warm on the outside and cold on the inside , Finns the opposite " .
From my years living in Germany I think he was spot on.
In general, what we consider a close friend would be thought of as an acquaintance .Took me 4-5 years to get used to but in the end I think it makes for a deeper life .
