They call it a wall, but it is a funny kind of wall. You might have seen them around. Crushed basalt rock sandwiched between sheets of reo. The sides go up, then the rock is added from the top. That’s the job of the gang, to hand the rock along the line and then up to the person on the ladder. I’m sure there are more efficient ways of doing it – elsewhere they’d be prefabricated beforehand. But that’s not the point.

I actually find it a little bit annoying when people who get all high and mighty and want to make some backhanded comment about my well-known business acumen say to me in that scoffing sort of tone: Leigh, let’s face it, you’d sell your own mother!
