Molly spread the blueprint across the table, tapping a finger on the backyard marked in red pen. "Bill, look at this. Twenty presents, minimum. Maybe more if the grandparents showed up." Bill leaned back in his chair, unimpressed. "It's a seven-year-old's birthday party, Molly. There's gonna be a bouncy castle. And clowns. I don't do clowns." "You don't do clowns? You robbed a bank dressed as a mailman last year." "That's different. Mailmen don't make balloon animals." Molly rolled her eyes and pulled out a second sheet, this one covered in tiny scribbled notes. "The presents table is by the fence, unguarded, right next to the cake. We slip in during the piƱata, grab the loot, slip out. Nobody even looks up." "And if a kid sees us?" "Then you do what you do best. Smile and lie." Bill smirked despite himself. "Fine. But I'm not wearing a party hat." "You're wearing the hat, Bill." "I am not wearing the hat." "The invitation says costumes encouraged. You're wearing the hat." He groaned, dragging his hands down his face. "This is the last kid's party we ever hit. After this, we go back to banks. Banks don't have clowns." Molly grinned, already reaching for the glitter-covered hat.
