Molly spread the blueprint across the greasy diner counter, smoothing out the creases with coffee-stained fingers. The laminated map showed the community center's birthday party setup in meticulous detail: bright balloons, scattered confetti, and an industrial-sized chocolate cake sitting vulnerable on a folding table. Bill leaned in close, his morning breath mixing with the lingering smell of stale fries and broken dreams. He tapped one grubby finger against the gift table marked on the diagram. "Saturday at two," she whispered. "Four minutes unattended." Bill scratched his grey beard. "You've cased this joint?" The plan unfolded with military precision. They would enter through the kitchen loading dock while the custodian took his smoke break, bypass the rent-a-cop by distracting him with a strategically dropped ice cream truck, and load every gift bag into their battered van. Molly checked her watch, calculating the escape route through the playground equipment. "Ninja outfits," she said. Bill blinked slowly. "Blend in. Be the entertainment." He nodded with the gravity of a man accepting his destiny. The clown car outside honked its rubber nose twice. Molly grabbed her duffel bag from the sticky booth seat. "Let's rob toddlers," she grinned.
