“Molly, if this kid’s party has one of those fog machines, I’m blaming you,” Bill whispered, crouched beside a glittery balloon arch. “It’s called atmosphere, Bill. Besides, you’re the one who insisted on roller skates.” “I insisted because the driveway is icy, and I’m not dying for festive loot.” “Please, we’re not dying, we’re debuting as invisible professionals.” Bill peered at the front door. “Invisible? My knees are loud.” “Then let’s use your inside voice.” Bill cleared his throat. “Okay, inside voice, I am a shadow, I am a whisper.” Molly grinned. “Good. Now, the presents.” “Targeting children’s gifts is morally questionable.” “We’re not stealing joy, we’re stealing packaging. The kids will still have fun. Technically.” Bill raised a finger. “Technically?” “Technically,” Molly said, pulling a tiny grappling hook from her bag, “we’ll replace the stolen gifts with… very similar paper.” “That’s not a gift.” “It’s a gift-shaped learning opportunity.” Bill sighed. “Fine. Step one?” “Disable the motion sensor.” “Step two?” “Locate the mountain of presents.” “Step three?” “Escape with dignity.” Bill looked down at his skates. “I have no dignity.” Molly winked. “You have momentum.”
