The community center smelled faintly of cheap pizza and overinflated ambition. Molly crouched behind the dumpster, studying the blueprints she had drawn in crayon, while Bill struggled to inflate a clown costume that was two sizes too small. The plan was absurd even by their standards, infiltrating a seven-year-old's birthday party disguised as entertainment. Molly had insisted the presents would be piled high near the bouncy castle, unguarded, glittering like pirate treasure. Bill was less confident, sweating through his red nose and squeaky shoes. Molly whispered, "Bill, we need balloons and fake mustaches for this job." He adjusted his wig and frowned deeply at the window where children shrieked with sugar-fueled joy. The clown on duty was already drunk on juice boxes. Bill muttered, "Kids are ruthless, Molly. One scream and we're toast forever." Molly grinned, revealing her masterstroke: a stolen invitation, a forged clown certificate, and a laundry bag labeled PRESENTS. Outside, parents filmed everything, oblivious. Stealing from children felt low, but rent was due. She checked her watch, calculated the exact moment the magician would fail, and nodded toward the unlocked side door with terrifying optimism. Bill sighed, grabbed the bag, and waddled toward destiny in oversized shoes.
