The endless swimming was a highlight of our three years in Singapore. On some Saturdays, we’d be in and out of the condominium pool four times. At dawn, when the boys and I’d occasionally happen upon whispering Japanese couples rounding out their evening with a bottle of breakfast Shiraz. Then we’d also dive in around midday, and driven by heat and claustrophobia, twice during the sultry afternoon. It was a theme park and often for us, an escape.

Early during our other-hemispherical stint, we were in the water, and I was talking with you about your birthday. I said, “How’s things now that you’re three? How’re you different?” Of course, your answer was instant, and assured. You replied, saying you were now, “Cooler than a robot, older than the wolf.” Not any wolf, mind you, but the wolf. I’d long suspected that you’ve a capacity for language, an opulent and striking relationship with words. Splashing about that muggy day, confirmed it.

Only a few months ago, and back in Australia, there was this domestic exchange. “Max, will you stop being so ridiculous?” It’s a word that’s vigorously employed from time to time in our house. But only as required. Ridiculous. You announced, “Mum, you’re ridiculous!” to which she said, “You can’t even spell ‘ridiculous!’” With sparkling comic timing, your retort came. “Yes. I can. M-U-M.” This talent, while sometimes maddening, might carry you far. It’s a gift.

A counterpoint to this linguistic skill is your love for engaging with the physical world. Moving like an inexhaustible machine, you explore, you probe, you pull stuff to bits. Inspired by curiosity, and bursting with a hearty sense of industry, you help me with jobs about the house. These are the moments.

One of my favourite things is when our world shrinks and shrinks, and it’s just you and I on a Saturday morning. A little backyard militia, we mow, and with a cutting wheel, we edge the lawns. All the while you question, encourage, engage. We sometimes visit the recycling depot, and lastly as a tiny reward, we pop by the Anzac Highway TAB, where in joyous imitation, you illustrate your fan of betting slips, resulting in financial return at least equal to mine.

It’s a routine that drapes exquisite meaning over these weekends. In a life often too complex, this fetching simplicity refreshes me like an oasis. We don’t often sit still on the lounge and chat, instead conversing while in motion. The car. With heaving backpacks, walking to and from school. Out the back, as Sunday shadows lengthen, playing cricket.

Last Easter, we wandered down to Glenelg Oval for the Sheffield Shield final. Strolling southwards, chatting; the breeze, the bent rays of autumnal sunshine. I love listening to your brotherly conversations, as these dance and hang in the air like bubbles.

If I close my eyes I can see a silent movie of flickering highlights, and these tumble about me, like rain.

You’re riding madly round the Old Gum Tree Park, with your feet dangling high above the pedals, and look, they’re now up on the handlebars as you wizz by in a mischievous blonde rush.

Lying under the patio, just after a December dawn, with summer’s heat already heavy in the sky, you’re hugging our new dog, Buddy and you’re talking to him like an equal, as if he’s a little brother. And, he is.

We’re on a Thai beach, and in a cocoon of pure, insubstantial now, you’re jumping like a kangaroo and laughing in the gently frothing waves. I barely believe we’re here.

Finally, you’re in bed, and I creep into your room, but there’s a thin shaft of light. Inspired by the nocturnal habit of Alex, you’re in your bunk, on your belly, immersed by a book, reading with a torch. This makes me happy.

Now exhausted, you finish your story, surrendering to our will, and within moments, you slide down into an irresistible sleep. You’ve interrogated your world, so delightfully, so energetically, across the long hours of the arching day that instantly, almost impossibly, you’re still.

You are now six, and will always be cooler than a robot, and older than the wolf. Max, we love you. Play on.
