I accidentally left my receipt at the self-checkout machine. A woman hurried over, waving it gently in my direction.
“You dropped this,” she said with a kind smile. I thanked her, tucked it into my bag, and headed home, thinking nothing more of it.
Later that evening, as I unpacked my groceries, something unusual caught my eye.
On the back of the receipt, written in quick, slanted handwriting, were the words: “Check your back seat.” My heart gave a jolt.
