If Scandinavia was a family
View gist:c552109b9d66e44d2aed
If Scandinavia was a family, Sweden'd be the obnoxiously anxious hipster older brother.
Denmark would be the hippie sister, smoking weed on her room while googling "dolphin telepathy".
She'd have a penchant for "funny" hats.
Norway would be the chipper healthy brother who's always out on some outdoor activity. He use the
mixer to do "nutritious" kale shakes.
Finland would be the alcoholic, solopsist brother whom nobody in the family really understand. He
collects knives.
Iceland would be the illegitimate sibling whom nobody ever talks about since he seems bat shit crazy.
Oh, I forgot Åland. She's the only genuinely healthy person in the family. She's boring,
conventionally pretty and likes to travel.
