One of the wierd things I have noticed with facebook is the way you get this “I wonder whether x ran into y” thought when you see that two of your friends are visiting the same place at the same time. For some reason it doesn’t immediately occur to you that just because you are friends with them doesn’t mean that they actually know each other at all, and are essentially just two strangers who are connected solely by two degrees of David Ramsay (with an obvious nod to Kevin Bacon).
Either way I hope they both enjoyed Darwin…
