A friend of mine recently said this:
Wouldn’t it be great if we could walk around in the world, and every time we see someone or pass someone, a little number would appear, telling us how many degrees of separation are between us? Then if we wanted to, we could try to figure out who we know in common?
That would be really fun. And I bet we’d be shocked at how many 2s and 3s there would be.
