Really? Funny. I lived in Sweden for a while and they considered Finns Scandinavian. The one Finn I knew didn’t complain but maybe he was just being polite.

Yanks sometimes treat Canadians like they are really part of the U.S. Canadians politely do not set them on fire when this happens. Skandian, Swedish, Norwegian, Danish, and Icelandic, are all closely related Germanic languages. Finnish is a non-Indo-European language, closely related to Estonian.
