In a northern town in Sweden, in the city of Umeå, it seems that it has become too cold to be able to say yes. They instead prefer to just do an inverted whistle? The word for yes in Swedish, "ja," apparently requires that you open your mouth, so these town folk have decided there needs to be a better way. So here it is!
So, how long before we all start "shooping" to say yes? I mean if the current cold trends continues, we might be doing sooner rather than later lol
