Bruce Perens looks a bit disoriented as he comes into the hotel lobby, looking for me. "Anyone here called Sam?" he calls out. The tiredness is evident on his face after the long haul from the US to Australia.

Moments before that I have looked around and, noticing a man pushing what looks like a luggage trolley, turned back to my magazine again as I wait for him to arrive. But then that happens to be Perens, returning the trolley without waiting for the hotel staff to do it for him. There's an air of having done this a million times before as he shakes my hand and we make our way through the lobby, looking for a quiet place to talk.
