So I thought this was an interesting testament to the randomness of Facebook and the allure of Six Degrees of Separation...
A friend of mine in college graduated two years ahead of me but had a sister who was in the same graduating class as me. We're Facebook friends. A few years back I saw in the Times Wedding section that the sister had married a Cushman (I think it was a Cushman, and not a Wakefield, but you get the idea). So I'm looking on Facebook and I saw an update from my friend and then clicked on his sister's page.
Randomly enough, she happens to be friends with a former client of mine (who I represented when she was selling her New York apartment before marrying into the Goodyear clan.)
A further random friendship? Joshua Bell. (As in, the violinist).
I'm always amazed when people you know, know other people you know but in a completely unconnected way. And then its always interesting when someone is friends with someone vaguely well known.
