Molly checked the toy-store map. “Bill, remember: we are stealthy, glamorous, and definitely not wearing matching clown noses.” Bill whispered, “I’m not wearing one. That’s a traffic cone accessory.” Molly crouched by the hedge. “Tonight we break in, steal all the presents, and leave enough confetti to look like a magical crime.” Bill adjusted his headlamp. “Confetti is the perfect alibi. Kids hate it.” Molly grinned. “Kids love it. Parents panic. That’s the synergy.” Bill held up a sack. “Where do we put the loot? In my hat?” Molly raised an eyebrow. “We use the sack. Your hat is for pretending you’re a friendly magician.” Bill nodded solemnly. “I am a friendly magician. My special trick is ‘vanishing presents.’” Molly listened for footsteps. “Okay, the door code is 1-2-3-4.” Bill murmured, “That’s probably wrong. People never use obvious codes.” Molly nodded. “True. So we’ll use 4-3-2-1.” Bill paused. “Are we… improvising? On purpose?” Molly hissed, “Improv is a skill. Now, when the birthday song starts, we move.” Bill whispered, “The song is called ‘Let’s Have Fun!’” Molly smiled. “Then we steal fun. Ready?” Bill swallowed. “Ready. If we get caught, I’ll claim I’m here for the piñata.” Molly patted his shoulder. “Good. Everyone loves a piñata expert.”
