“Bill, the presents are stacked by the cake.” “Molly, that’s because it’s a children’s party, not a warehouse.” “Exactly. Nobody suspects a warehouse with balloons.” “They’ll suspect two adults in tuxedos.” “Then stop wearing a tuxedo.” “It has pockets.” “So does a conscience.” “Mine is in dry cleaning.” “Listen. We enter disguised as entertainers, collect the gifts, and exit before the piñata.” “What are we entertaining?” “The children.” “With what?” “Magic.” “You can’t do magic.” “I can make your wallet disappear.” “That’s pickpocketing.” “Fine, comedy.” “You can’t do comedy.” “I’m hilarious when cornered.” “You’re cornered now.” Molly peeked through the hedge. Inside, children shrieked around a mountain of brightly wrapped boxes. “Plan B,” she whispered. “We have a Plan B?” “We return the presents.” “That’s not stealing.” “It is if we borrow them first.” “Borrowing implies permission.” “Then we’ll ask the birthday girl.” “She’s six.” “Excellent. Weak security.” “Suppose she says no?” “Then we give her a present: two adult men leaving immediately.” “Honestly, that may be the first responsible thing we’ve done.” “Don’t ruin our reputation.” “Wait,” Bill said. “I brought a present.” “What is it?” “A gift certificate for an apology.” “Molly rang the bell.” “Run,” she said.
