Just before midnight, we sort refuge in a church. Sanctuary. Like those immortal dudes in Highlander. Only with our own independent, freedom-camping, toilet unit.
Father Don Morrison took us in. Pulled no punches:
Had any French Rugby supporters been inside the Kea Kaha-Mobile? Said things like espionage and croissant? In French?
Oui.
Had any South Africans discussed their demolition of Fiji - and their false qualms about Namibia - within a ten metre radius of the Kaha's racy rear wheels?
Yes.
He didn't need to know any more. Sprinkled us immediately with some of Richie McCaw's bottled water. Recommended, as it was getting dark, that it would be safer to confront our World Cup demons in sunlight the next morning. Harry his dog agreed.
In truth, I'd struggled with my faith ever since Warren Jarvis kept hold of his communion host and swapped it for a K-Bar at lunchtime in Year 6. But whatever Father Don did, the results for the Kea Kaha-Mobile were immediate. Slime stopped oozing down the walls. That damp, hairy Asian girl who was always climbing out of the shower plughole packed up her deadly videotape and left.
The Kaha's spiritual index had been restored.
To celebrate Father D made us a cup of tea and sent us on our way. Wellington beckoned.
