Molly unfolded a crayon map on the alley bin, smoothing cake crumbs from the drawing of balloons, doors, and one suspiciously heroic pony. “Front gate’s guarded by dads with cameras,” Bill whispered. “We go through the hedge, grab presents, leave before musical chairs.” Molly tapped a purple rectangle. “Wrong. We enter as entertainers. I juggle. You make balloon animals.” Bill stared. “I can make one balloon animal. It’s a worm with anxiety.” “Perfect. Children love realism.” Rain ticked on the bin lid. From the community hall came shrieks, laughter, and the thunder of sugared feet. “What if they ask for rabbits?” Bill said. “Say the rabbits are invisible.” “That’s not entertainment, Molly. That’s fraud.” “We are stealing birthday presents, Bill.” He considered this. “Fair.” Molly produced two glittery party hats and a badge reading Professor Pickle’s Marvelous Fun Brigade. Bill put his on backward. “After the loot, we split evenly?” “Sixty-forty. I brought the hats.” “Fifty-fifty. I brought moral hesitation.” A small girl suddenly opened the back door, holding a cupcake. “Are you the clowns?” Molly smiled. “Absolutely.” Bill bowed. “And we accept payment in cake.” The girl nodded solemnly. “Good. The magician quit.”
