It's a cold Sunday afternoon next February, and you're about to push your usual mismatched Target sundries — lip balm, Coke Zero, bleach — down the conveyor belt when you grab one more item off an endcap: The Dark Knight Rises on DVD, on sale for $10. It comes back to you, the hot July expectation in those hours before you first saw how Christopher Nolan ended his Batman trilogy. "Do you want your soda left out?" the cashier asks. You pay and move on.
