Molly adjusted her fake mustache and peered through the hedge at the Hendersons' backyard, where forty screaming children orbited a bouncy castle like feral planets. Bill crouched beside her, wearing a foam crown he insisted was tactical. "That's a birthday hat," Molly whispered. Bill ignored this. He unrolled a crayon map of the yard, which was somehow the most professional thing about him. The present table sat beneath a unicorn banner, guarded by one teenage magician who was losing a fight with his own rabbit. Molly had cased the job for three weeks. She knew the cake arrived at two, the piƱata at three, and that parental attention expired after the second juice box. Chaos was her accomplice. "Ready?" Molly asked. "Born ready," said Bill, adjusting his crown. At 2:04, a clown burst from the shrubbery, and the children stampeded toward him. Bill gasped and clutched his chest. "Molly, I think that's my ex-wife," he whispered. "Good. She'll be distracted for hours," Molly said. Molly closed her eyes, counted to five, and dragged him toward the gift table, a black garbage bag billowing behind them like a flag of very poor moral standing. Somewhere, a distant toddler wept. Somewhere, a rabbit finally won.
