My DH won't have anything to do with food, so he doesn't see things like that. He will only throw something out if it is in full view and is completely mouldy (say, something in the fruit bowl).
These fancy chefs can always turn out picture perfect meals with a freshly-bought steak and a few sticks of asparagus - but it's a good housewife who can make something tasty out of a couple of wrinkly carrots, some potatoes which have started sprouting, and a tin of corned beef dangerously near its sell-by date.
My children,too, have annoyed me in the past when I've left out some blackened bananas on the side to make a cake with and when I go to do it they've chucked them out.
DH is forever fishing stuff out of the rubbish that I have thrown out (his old clothes and rusty gadgets) .
He will rake the leaves in autumn with a rake with only one tooth which is not properly attached to the handle, which takes ages. When I pointed out to him that they were on offer in a shop nearby, and shouldn't he get a new one, he said he'd already bought a new one, but wasn't using it yet.
Recently I sorted out my dressing table and put all the little tester packs and sachets of shampoo, face cream etc.,which I had been saving for short holidays, in the bathroom, and used them all up. There was enough for my daily ablutions for a couple of weeks.
So I must be a user-upper.
