Life in rural Wales comes with its own peculiar challenges, not the least of which is grocery shopping. When the nearest proper supermarket is a good thirty minutes away, online ordering becomes less of a convenience and more of a necessity. Jason and I have our system down to a science. The delivery arrives in stackable plastic crates, we unload everything, and then return the empty crates to the driver.

We even have our division of labor sorted. Jason tackles the refrigerated and frozen items while I handle the pantry goods. It works seamlessly... well, most of the time.

During our most recent delivery, Jason gestured toward what appeared to be a single crate sitting on our kitchen table. "That's all pantry stuff," he said casually, already turning his attention to the cold goods.

I nodded, reaching for the handles of what I presumed was one solitary crate. I'd taken precisely two steps when physics delivered a painful lesson.
