Finland would not be my first choice if I came from English speaking country or were looking for jolly life.
I am not a foreigner living in Finland so I can't talk from the experience but I can imagine what it can be like. I have lived abroad so I can somewhat compare.
For me this country, although I love it, is more like a place of work. People used to be quite social in the old days or so I've heard from the stories. But as people moved to the cities I feel this has been lost, a little bit like how the food was ruined at the same time due to health program. As the butter and salt was taken away, the food became bland. And same happened to the people.
The older people and many of the young ones have reserved view of the foreigners. I can understand it for the older people. I will take my father as an example. He lived his youth in a house without electricity (in the 60's) far from any major cities like many of his generation. He has never left the country. Also in a family where work was appreciated and fun, like alcohol, was frowned upon. Now as you can imagine, when they moved to the cities they didn't really bring any kind of light of liberalism or continental mannerism with them. They were hard workers and so they tried to bring up their kids (however the welfare state has a bit ruined this aspect). I didn't spent my holidays (in the 90's and 00's) in the beach, instead we spent time on our family estate cutting trees, collecting berries and fishing. This was in the east, the social part of the country. The reservedness and attitude grow further you travel south and west (except when you hit fennoswedish coast). But as another side of the coin, further you go east and north, the less people have experience with foreigners. It was quite a talk when one of my cousins decided to marry a Spaniard. Yes, even white Europeans can be exotic in certain parts. Now imagine coming from Africa.
For the mindset: feelings and such does not enter their talk. Open shows of affection neither. Never as a kid saw my father kissing my mother or confess his love (they kept it personal and in their bedroom). Now as you can Imagine, after such upbringing I personally aren't any kind of open romantic either. I feel Finnish itself is unsuitable for speaking about feelings and such. It would be much easier for me to use English in such situations.
Now if you want to come here, don't try to blend in too much. This way you can distinguish the real people from the bigots much easier. You will find the people who will enjoy being talkative and want to get to know you, although not easily. If you come here to learn about the country and don't expect too many nice things from the people and the country, you will succeed. But even after success the country won't become similar to other Europe.
Yup.
