The community center on Maple Street had been transformed into a pastel nightmare of streamers and balloons, with a hand-painted banner reading Happy Birthday Leo sagging optimistically over the entrance. Molly crouched behind her aging white van, peering through binoculars at the folding table heaped with brightly wrapped boxes. Bill sat beside her, attempting to inflate a balloon that kept squeaking in protest. Their plan was simple on paper and humiliating in practice. She had cased the party last week while pretending to be a prospective parent touring the facility, noting the blind spots, the overworked entertainer, and the single harried mother guarding the juice boxes. The presents were piled near the back door, conveniently close to the parking lot, as if the universe wanted them stolen. Bill was already sweating through his striped shirt, which Molly had purchased from a discount costume shop that morning. The van's side door was wedged open, ready to receive the haul. Outside, children shrieked with the unfiltered joy of too much sugar and too little supervision. A clown on stilts wobbled past the window, and Molly felt a flicker of doubt about their chosen disguises. Still, the take promised to be substantial, with at least fifteen large boxes and a suspiciously lumpy gift bag that probably contained cash. She lowered the binoculars and turned to Bill, who had finally succeeded in tying the balloon, only for it to immediately pop. "Bill, we are stealing from a five-year-old's birthday party." "Technically we're stealing from the parents who bought the presents." "That does not make us sound better, Molly." "Relax, it's not like we're taking the cake." "We are taking everything else, including the cake if it fits in the van." "It's a bouncy castle, Bill. How do we even get in unnoticed?" "We dress as clowns. No one questions clowns at a children's party." Bill stared at the rubber shreds in his palm with the solemnity of a man holding his own future. The parking lot smelled of hot asphalt and spilled lemonade. Molly checked her watch; the donkey game was due to start in three minutes. From inside, the off-key chorus of Happy Birthday began, giving them their cue. They pulled on red noses that pinched painfully and oversized shoes that flopped. Bill slipped twice. Molly steadied him, sighing. Somewhere a child yelled that he wanted cake, and another shouted louder. "I am terrified of clowns and I am a criminal." "Perfect, then you'll be convincing. You look haunted." "What's the exit plan when twenty sugars-high kids start screaming?" "We grab the present table during pin the tail on the donkey and run." "That's your master plan? Steal presents while they're stabbing a donkey poster?" "It's elegant, simple, and the parents will be too distracted to notice." "Fine, but if I make balloon animals, I'm keeping the tips." Their moment had arrived, absurd and glittering, and they shuffled toward the back door like very guilty, very unfunny clowns ready to steal childhood itself.
