One other anecdote from that, I think is perhaps relevant to the theme of these things. At one place we went to a school that had newly been built. There was a headmaster there and he'd been asked why is it that when you come into class you lift your cap to the boys and you say, 'Good morning, boys', and they say, 'Good morning, sir'? And he said, 'I do that because for all I know there might be a future Prime Minister amongst these boys'. And that's actually not so far fetched as it seems because some of these towns were very small but Robert Menzies, who was perhaps one of the best known of Australian Prime Ministers and the Prime Minister during the war, he was from just such a school in Jeparit, where we stopped for a day, near Warracknabeal. And it shows that one should treat all these people with respect; they might just be people of importance, and even so of course, whether they're Prime Minister or not, they're going to be doing valuable things.
