When I asked this week how much she had earned from the race, she reckoned she still didn't know, and seemed to care even less.
Actually, it was $20,000 (£12,670), probably more than she'd earned in prize money in eight years on the international circuit. "Well, I'll pay off some of my mortgage, then. Got a big enough one," she smiled.
On Wednesday, just three days after the race, she was back at school for a staff meeting, but she did miss the start of term, having been given time off to compete in tonight's Golden League meeting in Brussels.
The school's very supportive, she says, but wasn't she now tempted to give up work to pour everything into what could be her last Olympics?
"Not a chance. I don't know how many years I've got left in the sport, maybe only one, who knows? So what am I going to do? Watch afternoon telly? Mind-numbing. For some, running's all there is in their lives.
"I love running but I've got a life outside of it. I'll give everything to have a successful Games, but I have to switch off from running some time, otherwise I'd be a basket case."
She tried going full time back in 1998, when she was Hayley Parry, then a Loughborough graduate teaching in her native Swansea. "I got injured and knocked it on the head after six months. It was so tedious, sitting around doing nothing. I'm not that sort of person. I actually like tidying the house," she recalled.
Instead, she moved to Surrey, married Ian Tullett, a British pole vault international and fellow teacher, and went back to work.
Her subsequent track career - under the tutelage of former Olympic steeplechase bronze medallist Mark Rowland - has had its ups, with last year's Commonwealth Games silver, and its downs, when she tripped over in the Sydney Olympic final and then pondered quitting during a 2001 season in which she competed while unaware she was anaemic.
While hovering on the edges of world class, she was still probably best known for her anti-drugs protest with her mate Paula Radcliffe at the Edmonton world championships, demanding "EPO Cheats Out".
Tullett deserved this breakthrough for a career in which she's always been a real trier. She modestly shrugs that Sunday was just a day when everything went "100 per cent right - physically, mentally, tactically" and smiles that it might well not happen in Athens. Yet how did she manage to get it so right when so many more-lauded, younger team members got it wrong in Paris?
"Well, I don't think we did too badly in Paris. A final is like entering a prize draw, everyone's got a chance. You want to win, you're trying to win, but not everyone can win. You need a bit of luck." Yes, but she didn't mention the bit about needing real heart and courage.
"Well, if people were inspired by someone like me winning a medal then great, but I wouldn't ram it down their throats. It was just another race - only it was called the world championships."
Anyway, shrugged Mrs Tullett, now it was more important to make sure the Hoe Bridge Under-10 netball girls maintained their unbeaten record.
