Translation:The strange Finnish man wants to live in Sweden.
I don't think so (especially since literally 100,000s of Finnish people have emigrated to Sweden over the years).
I think it refers to Vadelmavenepakolainen by Miika Nousiainen, a (play and) book where a Finnish man is obsessed by living in Sweden and becoming as Swedish as possible, even going to great (and criminal) lengths to do so. He's not strange because he wants to live in Sweden. It's the level of his obsession that is strange about him.
OH ok, it is maybe a literary reference this time. But there's stille kinda a rivality between Finland and Sweden and the Finns are saying like: "Sweden is shit" and stuff like that. (eg. this two memes : https://www.instagram.com/p/BrAStRaBbyO/ and https://www.instagram.com/p/B1Omi6fhZB8/ ). And thanks for the literary reference, I am gonna check it some day!
It depends. I once had a dog (French dog, briard) that liked to sit in the sauna with other people.
And - this is true - in the past, horses were also washed in the sauna after people. (It wasn’t very common, but it makes a lot of sense because horses sweat (and cleanse) the same way people do.)
After the sauna to swim.
Sweden is our dear enemy. We don’t hate them, but we still bark. Maybe because they’re a little better at ALMOST everything. But we love Norwegians because they also always bark at the Swedes. And they, too, have long been under foreign rule. First Denmark, then Sweden. And even the Nazis occupied Norway in World War II.
