Hi Neil, I've emailed you. Six degrees of separation refers to the idea that everyone is on average approximately six steps away, by way of introduction, from any other person on Earth, so that a chain of, "a friend of a friend" statements can be made, on average, to connect any two people in six steps or fewer. ;-p
Hi Neil, I was travelling back out to Tunisia today and left home at midday so missed Pat's msg but she has contacted me on FB asking if I received it. Will speak to her tomorrow np. Small world - what is it they say about 6 degrees of separation?
