Molly spread the hand-drawn map across the hood of their dented minivan. Crayon smudges marked the entry points. Bill squinted at it, holding his reading glasses with one hand and a juice box with the other. "The bouncy castle goes up at noon," Molly said, tapping a purple blob on the map. "That's our distraction window." "What about the mother?" Bill asked. "She looks like she does CrossFit." "Karen will be busy refilling the lemonade station. I timed her last Saturday during the rehearsal party." Molly cracked her knuckles with theatrical menace. "We go in through the garage, grab the gift table, and load everything into the van before the piƱata drops." Bill sucked the last of his juice box dry with a long, sad gurgle. He studied the map again, rotating it twice before realizing he had been holding it upside down. "What if a kid sees us?" "Kids love strangers carrying large bags. We tell them we're Santa's helpers." "It's July, Molly." "Kids are stupid, Bill." He considered this with the gravity of a man who had once been outsmarted by a revolving door. Finally, he nodded. "I'll wear the elf shoes." "That's the spirit."
