There is a continuous sequence of connections between all of us – “six degrees of separation” some have called it – and yet we seldom bother to look in the mirror and try to make sense of them. Like that song: “the foot bone connected to the ankle bone, the ankle bone connected to the leg bone, the leg bone connected to the knee bone”, et cetera, et cetera. How can we go on without recognising each other? And yet, willy-nilly, we do.
