I assume Helsinki is the most densely populated area of Finland, but even here the streets are nowhere as crowded as in London, Brussels or Firenze to name a few. This may have something to do with the temperature but I have to keep reminding myself it’s october already, so holiday season is over.
Still, even if there were a lot more Finns on the streets, I doubt you would notice. At first they seem silent and private but as soon as you talk to them, they tend to be very open, humorous and kind. In short, they are my kind of people.
