Cooler still was the response from the Wanaka community. Local club stalwarts laid out cones and found balls, games of touch materialised among the throngs, the sun beat down on the Upper Clutha fields and, in the middle, bouncing about through the laughs and the noise and the chaotic joy of it all, Smith signed shirts and gave tips and, most importantly, gave a little bit of himself to make a big difference.
Smith has come of age in a time when rugby is a job; an increasingly corporatised spectacle that straddles the inimical pursuits of global revenues and community engagement. Moreover, he is a superstar of the sport, an athlete who, in the hands of other codes, or other countries, might well be cosseted in some plush suburb replete with security phalanx and price tag attached to any public appearance. Thank goodness he's here, ours, and him. And thank goodness we still value these acts of kindness.
Compare this story with another this week, namely the moaning of Mourad Boudjellal, the brattish overlord of French club Toulon. Boudjellal, who has collected players and titles in the way spoiled children collect supermarket toys - namely, to boast to other kids that they have the complete set before tiring of the trinkets and moving on to the next thing - is apparently unhappy with the form of, among others, Ma'a Nonu. Spare me.
The problem with men like Boudjellal is they are incapable of valuing anything that does not sparkle on demand. Worse, there is no glory unless it is reflecting squarely on them.
I doubt Boudjellal would care much for Ben Smith's actions this week. I doubt he would realise that this foreign legion of players he so boastfully amasses would be much more comfortable in the community, sharing their time with the local kids, as Nonu did so often in Wellington, without demanding a thing in return. That's what the game is about. That's what makes it special. That's what he will never understand.
Fortunately, 30 years from now, Boudjellal will be a footnote in the history of French rugby. But I suspect - no, I know - that 30 years from now, at least one of those kids who yesterday scurried about on a summer's day in Wanaka with their mates and with Ben Smith will see another story like Kade Lawrie's and smile fondly at the memory of that time their (still) favourite All Black pitched at the Upper Clutha Rugby Club, a hero. For more than one day.
