Maybe a text exchange with Tiger Woods. Or a few messages from a music megastar. They're about the only times Jordan Spieth takes time to ponder how far - and more importantly how fast - he, as world No.1 with a bullet, has come.
Whether he gets flustered by anything else is debatable. Certainly nothing seems to faze him down the stretch on a Sunday afternoon. But the man who sauntered back into Sydney, the scene of his Australian Open triumph 12 months ago, which started his ascent to the top of the charts, is certainly big business now. 
"A few years ago I was sitting in a high school classroom and now we're here," said Spieth after cramming in nine holes on Monday at the Australian Golf Club, the scene of an exquisite final-day 63 last year.
"For the most part when I'm at the course, it feels normal, which is what's most important to me. A lot of the times off the course I'll sit back and, whether I'm trading texts with a music star or Tiger, whoever, you sit there and say, 'wow, this is actually kind of crazy when you think about it'."
Spieth's first appearance in front of the Australian media was a carefully stage-managed appearance for Under Armour before the opening of Rebel's new Bondi Junction store later this week.
The apparel giant has NBA MVP Stephen Curry, NFL MVP Tom Brady and MLB MVP Bryce Harper on its books. Spieth could be considered to be as big as all of them - at least on a global scale - and speaks as well as any.
Like Rory McIlroy before him, Spieth arrived in Australia last year as potentially the next big thing and returns having been christened exactly that. And there is improvement to come, if that is possible.
Yet it is something other than his US Masters and US Open successes which make the 22-year-old so likeable. At least to Australian fans.
It was only a small "thumbs up" - nothing more - as the previously major-tortured Jason Day made a putt from another postcode and a simple tap-in on his next stroke during a watershed US PGA win with the American in tow.
In the most intense of environments it was the most revealing of gestures. There is a sportsman there too. "Here in Oz the people remind me a lot of home in Texas, they're nice genuine people looking out for others," Spieth said. "It seems like when the Aussies are over in Texas, they really enjoy being there maybe over anywhere else. I'm not speaking for all of them, but certainly a few have mentioned that and quite a few live there."We love coming over here. For us it's very different with the style and vibe, but at the same time you have the same genuine people we're used to and that's what we enjoy. You don't necessarily get that everywhere else so that's cool."
Day might not be here - he has skipped the tournament for the birth of his second child Lucy earlier this month - but he will be back. Rivalry? Spieth likes to think it is friendly, but there is no doubt the new generation of 20-somethings will be back creating waves again next year.
"At the end of the year I'd played so much with him I had dreams of him saying, 'Jords, have a good day today'," Spieth joked. "I'm certainly jealous of how far he hits the ball and what a great ball striker he is. He's a big-time threat. He's as big a threat as anybody.
"There were so many different comparisons this year ... me with Rory, me with Jason, Jason with Rory, Rickie [Fowler as well]. Golf is is a good place with a lot of young players that are fearless and wanting to perform on the big stage. There will be some bouncing around at the top of the rankings and I'm hoping we can all get into contention with each other."
