The unwritten rules of behaviour are infinite in number, finely shaded, and subtle to the last fraction of a degree. They are not to be broken. If broken, the rules of forgiveness leading to re-establishment are equally of air and iron. I learn these rules with rather less ease than my contemporaries because, in the back streets of my being, a duel is developing and increasing in fervour between my instinct which knows why something is so, and my hen-pecking intelligence which wishes to analyse why something is so.

This silent cry is of ecstasy for what has been done, and of despair at being forestalled, and being thus forewarned, that neither This Year nor Next Year am I to have the ability and wisdom to light the lamp on my own. Although one branch of childhood is in this fashion lopped for all time, the rest of it still inhabits the body of a child which occupies itself in childish matters.

I immediately cotton on to the fact that intelligence thus lightly used, and one-upmanshipishly displayed, is a birthmark giving me a two-coloured face, is a goitre, a hump on the back, webbed toes, and makes me stink like the night-man. Once again I learn what I knew on my very first day at Kensington School, and have carelessly forgotten, that it is more intelligent to appear less intelligent. I henceforth rein myself in, and publicly give back only what I have been given - fifty-six for seven- eights.

The Australian form of self-respect, however rough-and-ready, heart-of-gold, come-and-take-pot-luck-with-us, and matily extrovert it is, essentially, genteel, ingrowing, self-pitying, vanilla-ice-cream hearted, its central fear a fear of intellect.

While still sixteen I am put in charge of a class of forty children who are two, three or four years younger than I. I fall in love with them. They are my possession, my mob whose forty minds, under my flashy and domineering control, are to become one, a mind unsullied by errors, unmarked by blots, contaminated by misplaced originalities outside the curriculum, and as full of facts as a pomegranate seed.

I cannot consider fighting in competitive Manly Fun any more than I can consider pitting my running, swimming or climbing body against other bodies. Nothing, then, or now, arouses me or will ever arouse me from a perfect disinterest in ball games.

Now, I can smile at the stock quality of these friends, these uniforms. these looking-glasses, these sharers. Each is a character lifted straight from literature and yet, life successfully aping art, they are alive, and fulfil their destinies - or act their parts - flawlessly.
