I happened to be in the right place at the right time recently and got to be present for a talk where we were asked who we were. I answered (in my head of course as I’m sure the several rows behind me didn’t want to know who I was!) initially by saying “is it a trick question? It’s too simple, I’m me and you are you”. And then immediately afterwards the penny dropped, it dropped so far down that you could almost hear it land in the silence. Those same depths to which the penny dropped made me realise just how deep the question actually was, simple it was not! Don’t get me wrong...
