Molly and Bill crouched beside the tent. Molly said, “So, the presents are inside, and we’re going to take them.” Bill said, “Every single one? Even the lumpy package that sounds like a kazoo?” “Especially that. It may be valuable.” “Molly, these are children’s gifts. I’m not sure my conscience can outrun a kazoo.” “Then don’t run. Walk confidently.” “That’s your plan?” “No. My plan is to announce we’re the entertainment committee.” “You’re wearing a lampshade.” “It’s a hat of authority.” “And I’m holding a cake?” “A convincing cake.” “It has a candle stuck in my sleeve.” “Then you’re the birthday wizard.” “I’d rather be a wizard who doesn’t steal from kids.” “What if the children recognize us?” Bill asked. “Then we’ll apologize and ask whether anyone needs a volunteer to test the presents.” “That sounds suspiciously like doing something useful.” “I contain multitudes. Also, I’m hungry.” “If we’re caught, I’m blaming the cake.” “Deal. But if it’s good, we’re taking seconds.” A child called from inside. Molly said, “Fine. We’ll take one present, leave a note, and—” “Or we could leave the cake and go.” “Who wants cake?” called the child. “I do,” said Molly. “Then we’re stealing nothing,” said Bill. “Not even the kazoo?” “We’ll borrow it for one song.”
