Molly spread the blueprint across the table, jabbing a finger at the little square marked "gift table." "Bill, look at this. Twenty presents, minimum. Maybe more if that kid's got rich grandparents." Bill leaned over, squinting. "It's a seven-year-old's birthday party, Molly. Not Fort Knox." "Exactly why nobody's guarding it," she said, grinning. "We go in through the backyard fence at three-fifteen, right when they're doing the piƱata. Everybody's distracted, eyes on the candy raining down." "And the costumes?" Molly pulled two crumpled outfits from her bag. "You're the clown. I'm face-painting lady." Bill held up the rubber nose with visible disgust. "I am not wearing this." "You want the loot or not?" "Fine. But if one kid asks me to make a balloon animal, I'm walking." "You'll manage." She rolled the blueprint back up. "In, out, presents in the van before the cake even comes out." "And if someone recognizes us?" Molly smirked, tucking the plan under her arm. "Nobody remembers the clown's face, Bill. That's the whole point." He sighed, pulling the rubber nose over his own. "The things I do for gift-wrapped electronics."
