You will be familiar with the concept of ‘six degrees of separation’ – the idea that the world’s population (or Kevin Bacon’s co-stars) can be joined together by six relationships. In my experience, between Danes, the degree of separation is three, perhaps fewer. When two Danes who do not know each other meet at a social gathering they will take, on average, no more than eight minutes to discover either a direct mutual acquaintance, or at the very least a friend-of-a-friend connection (I have actually timed this). More than three degrees of separation is genuinely rare.
