Some stories are 1 part mystery 1 part romance or 1 part danger 1 part triumph. This story is 1 part shopping 1 part stochasticity.
On a Monday afternoon a young couple goes into Costco. They shop happily enough, joking and sampling, agonizing about whether to get guacamole, unaware that disaster is so near. They purchase their few selections and enjoy some food court refreshment, still unaware of the DISASTER lurking. They approach the exit, receipt ready. She begins looking in her purse, “Why can I never find my keys?!?!” He looks to his right, past the girl, eyes lazy but something gets through. “Those kinda look like your keys,” he says, also lazily. Ice cream and heat make him lazy. She looks, “OMG!” They step slightly out of line. The customer service woman hangs up. “These are my keys.” “They were found outside.” “Do I have to show…” “No.” They rejoin the line and live happily ever after.
