Exactly five minutes later, he did the same thing. Five minutes later, the same. And so it went.
After this happened for the tenth time, I asked Scott why he was doing it.
In a calm and somewhat self-assured manner, he simply said, "to keep the tigers and dragons away, to stop them from eating me".
I let the matter rest, despite the fact that the threat of such an attack was, well, seemingly very low. But what did I know?
As the trip continued, the spectacle continued, with Scott jumping up every five minutes, screwing up the paper and throwing it out the window.
Finally, we made it into to the station at Alice Springs. What a journey. As we were getting off the train, Scott had a rather self-satisfied, smug look to him.
"Ha", he said, "it worked! We made it and not a tiger or dragon in sight".
Which just goes to show how successful some strategies can be, at least in the minds of some.
