Patricia MacLeod, a 74-year-old retired pensioner from Wagga Wagga, New South Wales, had spent her entire adult life being careful with money.
She clipped catalogue specials. She bought markdown stickers at Woolworths without a hint of embarrassment.
She cooked from scratch every Sunday and stretched every meal into two. Her late husband Brian used to joke she could feed a town on what most people threw out.
But lately, something had changed.
It started when Patricia bought a kitchen scale from Kmart one afternoon in January.
A cheap twenty-dollar thing, the kind that runs on a single battery and shows weight in grams. She'd seen people on the internet weighing their food waste, and something in her wanted to know — really know — what she was throwing away each week.
She kept a notebook beside it.
Every time something came out of her fridge and went into the bin, she weighed it. Wrote down the date. Looked up what she'd paid for it on the docket. Wrote that down too.
A bag of salad opened on Wednesday, slimy by Saturday. $4.50.
A punnet of strawberries from Woolworths, full price $5.99, fuzzy on Wednesday. Most of them tossed.
A piece of cheddar she'd bought on a markdown sticker for $6, fuzzy edge by day five. The whole thing in the bin because at 74 you don't eat around mould.
A litre of milk, still days from its date, that smelled wrong by Wednesday morning.
Leftovers from Sunday roast that had a faint sour edge by Tuesday lunch.
Patricia tracked it all for 8 weeks.
Then her sister Maureen called from Albury on a Tuesday afternoon. They'd been chatting about food budgets, and Patricia said, "Hold on Maureen, I want to add something up."
She got the notebook. She started counting.
$94.60 a week.
Patricia sat at the kitchen table for a long time after that. Maureen had to phone her back later because they'd been cut off and Patricia hadn't even noticed.
$95 a week. Nearly $380 a month. Over $4,940 a year going straight into the bin. On the Age Pension.
She felt her face go hot. Not from the money exactly — though the money mattered terribly. But from the years she'd spent telling herself she was being careful while the truth was rotting in her crisper drawer every week.
She wasn't lazy. She wasn't wasteful by nature. The food was simply going off before she could eat it.
Something invisible inside that refrigerator was destroying nearly a fifth of her groceries every single week.
And it had been doing it for years.
