That’s something we go through here, because MrsT will buy things like that (cookies, especially), and then hoard them, refusing to open them and saving them “for later…,” which is never defined.
I’m the opposite - once something is in the house, I treat it like a job to consume them - “Right. There are 36 cookies in that package. The package says a serving is 2 cookies. I shall have 2 cookies a day until they’re no more, whether I want them or not.” - and that’s what I do.
I’ll even tell her, “The cookies have been opened. I’m eating 2 a day until they’re gone, so if you want any, you better stick up for yourself.”
You know how every Christmas, I post a picture of the 12 or so boxes of Christmas-themed cookies we buy…and how in June, I’ll post pictures of how we still have 10 boxes?
That’s down to MrsT saying, “Don’t open those. I’m saving those.” and then leaving them to sit, month after month - for what are you saving those?! Now it’s June and we’ve got 10 boxes of stale cookies that we could have enjoyed when they were fresh.
