Customers shuffle. The line grows longer. You watch from behind as Lizzy fumbles in her purse, whispering apologies. Cashier (mildly annoyed): Sorry, you're short. Lizzy (nervously): Let me check again—I think I have some change... She empties a handful of coins onto the counter, sorting with trembling fingers. Her three kids watch quietly behind her, knowing this moment all too well. Lizzy: Okay… okay, I’ll put something back. Just… not the cereal. Please. She looks up at the cashier. Lizzy: I’m sorry. I’m really sorry.
