I think the funniest paper list story I have was from probably three or four Christmases ago.
I was making a special run to get all the things I needed for our Christmas Day dinner, and I knew I was going to only one store, so I didn’t need to comparison shop, and it was a lot of items, so I carefully constructed my list on a regular-sized piece of notebook paper (8” x 10”).
That paper was unwieldy, so every few items, as I moved around the store, I’d tear a strip of the paper off, wad it up, and toss it in one of the many trash bins placed around the store.
I shit you not, I got to the home stretch, checkout registers in sight, list gone at this point, and I remembered a single thing I wanted spur-of-the-moment, so I parked my overflowing cart to the side, well out of the way, and trotted off across the store to grab my one little specialty item.
Came back…no cart! Looked left, looked right…no

cart! Either someone had walked off with it by mistake (hard to believe with a cart so full), or a do-gooder employee thought it had been abandoned and grabbed it. What?!?!
I immediately set out to find my cart, and this was the international market, so the size of a football stadium, but Kris Kringle wasn’t favoring me, and I never found my cart.
I had no choice but to try and remember my list, and most days, I’m lucky if I can remember where my butt is, so that was a trial. I kept texting MrsT and telling her to snap a pic of this recipe and that recipe, so I could go through and use them as memory ticklers to get what I needed, and I did manage to remember about 75% of my original list.
