No you're not stupid. lol I'm of Scandinavian descent too, Swedish, Norwegian and Danish and I do not know any of those languages. My grandparents spoke it and had thick accents but they are long gone.
@SW-User @JacobMacon Difference for me was my Dad spent his childhood there and came to US as a teenager. If it was just my grandparents, I’m sure that I wouldn’t know.
@JacobMacon My Dad’s heritage is Norse Scandinavian, so our ancestors were not indigenous to Iceland. More than likely Norwegian Vikings that settled in Iceland. The Vikings sort of got around and stuff. lol 🦋
My family line is a mix of Scottish, American and Japanese but I don't know any Japanese :) It's not stupid, you don't need to know a language because you are genetically related to someone who speaks (or spoke) it
