There will be tears from Timmy tonight
After all the build-up, it was a throwaway line from one of his children that made Tim Cahill realise this really is the end.
Cahill's eldest was only a year old when his father made his debut for Australia - pretty much all his children's lives, their dad has been a go-to man in green and gold.
They won't be the only ones who have to get used to a change in circumstances.
A five-minute cameo Tuesday night against Lebanon will allow the 30,000-odd present to show their appreciation, but the memory of Cahill's 50 international goals will linger for much, much longer.
Not that Cahill Sr intends to bow out quietly, as he takes a quick break from the Indian Super League to sign off for Australia.
"Even when I scored in the ISL the other day, the comment from my children was, 'Dad, are you ever going to stop?' " Cahill said.
"Nobody can take my appetite away, and at 39 I feel great. Scoring goals is what I do. Even if I just play for five minutes against Lebanon, everyone expects me to create a chance or score.
"I want to make sure that whoever is out wide, when they cross the ball in, I'm on the end of it. I'm sure I'll get a chance, because I have for my whole career."
The facts of that career don't disagree, but for once Cahill will deal in feelings rather than figures once he's called from the substitute's bench tonight.
"This is probably the first game when I can let my emotions run free," Cahill said. "I'm not usually hugely dictated by my emotions, apart from when I score - other than that it's always business as usual.
"There could be tears in my eyes at the point I come on. I've had a lot of highs and lows for my country, overcome so many obstacles, it will be an amazing moment to know it's all coming to an end.
"There's no better place to bow out, and I'm really grateful to the squad and to Arnie for accepting me, that's a massive thing for them to do."
After this game there will be a dozen more in the ISL, before thoughts turn to what comes next. But Cahill is in no rush to get through this interlude.
"In India there's no pressure on me, no preparing for the Asian Cup, no one saying I'm too old," he said. "That was the story of my life which was what made the big moments all the sweeter.
"Over there I'm enjoying life, enjoying being a marquee player, and enjoying being second in the league."
