Maybe you are an exchange student; maybe a tourist, or someone just interested in Finland and the Finns; and maybe you are a Finn that never dared to ask this one question: Why Finns don’t talk?
If you are a Finn, you probably never asked the question because Finns don’t talk. Not about things like this. The reason is a very deep and philosophical one: human communication is imperfect. An example —
A Finnish man asks his friend whether or not he should propose to his girlfriend. The friend mumbles: “Hell, yeah. What a prime idea.” The friend, confident that his tone was easy enough to understand, shouts for more beer and drops the subject.
Consequently, the Finn proposes and is rejected: the girlfriend’s shrill and forceful communication is quite easy to understand. The Finn leaves, heartbroken, and after three days notices that his sorrows float, and thus cannot be drowned in alcohol. Paying the bartender, he has a sudden epiphany: people are the source of all his problems! Thus he utilizes an axe on both his friend and girlfriend.
And so only the one with worst communication skills survives to breed. Indeed Finland is a vicious downward spiral.
Or: Finns don’t talk because talking means communication, and communication always holds the seeds of misunderstanding, offense, and grisly axe-murders. It’s not a good idea to offend anyone in Finland: just think of all the sharp instruments and the blunt ones, the aggressive drunken people, and the empty places where no-one can hear you scream.
And so Finns avoid speaking, being withdrawn and introspective by nature, and having little opportunity or inclination for honing their communication skills. For them, all is fine as long as one can point at a beer bottle and grunt: the cashier will understand.
After several years of this, only the grunt is needed — a man walks in, snorts, and places a bill on the counter. The cashier hands him a sixpack, gives change, and they part, without speaking a single intelligible word.
A few years more, and even the grunt disappears.
And if the years pass along, bringing with them a voluminous beer-gut and many interesting health problems, sooner or later there will be no bill either — and then no beer.
Oh, the manifold tragedies of Finland.
(Shocking expositions of some other reasons why Finns don’t talk might follow later — like the foolishness of keeping your mouth open during winter chills, and the evolutionary pressure caused by the talkative ones attracting bears and, if any of the tribe survived, being cast out after the bear had eaten its fill.)
