Settle down, breathe through your nose and, if you must show your emotions, keep it to a clenched upside-down smile like All Black coach Graham Henry's. It was only a Rugby World Cup pool game. The path to the final is still strewn with banana skins.
But for the Henry-sceptics, those of us who thought he and his sidekicks were lucky to hang on to their jobs four years ago, it's time to acknowledge the All Black coaching trio have got the odd thing right.
One is their recruitment and development of Sonny Bill Williams.
Henry's stock role is as the headmaster he once was. That smugly firm-but-fair persona with his pronouncements on what is "pleasing" or "disappointing" can pall, especially if you ever rubbed a headmaster up the wrong way yourself.
But when he got a sniff of the supremely talented Williams wanting to be an All Black last year he turned sweet-talking salesman, rolling out the welcome mat and patter for the player and his agent, Khoder Nasser. Never mind whether it looked a little undignified for an All Black coach, Henry did what it took to get his man.
