I imagine your wife tosses things out the second they are expired or even 1 day before. Or is she even allowed to open the fridge?
Lucy is not allowed in the kitchen, much less the fridge. When we were dating 20 years ago I opened her fridge to find crap that had expired 5 years before. The smell was awful. I threw everything out and cleaned the interior.
When we got married it was time to sell her pathetic shack of a house. I reached down into the lower cabinets to see if there was any stuff we could use. I saw a Fry Daddy deep fryer. It wouldn't come out easily so I tilted it sideways and rancid oil spilled out.
Me: "Why is there oil in this Fry Daddy?"
Lucy: "Because I had a party and they said you could save the oil."
Me: "When did you have the party?
Lucy: "About 4 years ago."
