You know how the conversation goes, "Oh, you're from Australia? Do you know X? He's from there too."
And you carefully explain that no, you don't know X. (And is it any wonder, when the population of Australia is over 20 million...)
So I am wondering how the conversation went when a Malaysian friend of ours, who was staying at a youth hostel in London, bumped into my Australian niece there, whom he hadn't previously known existed, and they both found out that the degree of separation between them was ... 1.
So what's your story about a huge coincidence?
