Molly and Bill crouched behind the garden fence watching the bouncy castle wheeze. "Bill, we cannot just walk through the front door carrying empty sacks at a children's party." Bright presents towered beside the juice boxes, untouched. Bill adjusted his fake moustache while Molly checked the getaway wagon, a rusted tricycle with a squeaky wheel. "We will dress as entertainers. I own a terrible balloon dog and a vanishing cape." The birthday music thumped loudly as children screamed happily around the clown. "Your balloon animals look like sad potatoes and your cape smells like onions." "The kids will be distracted by cake. We grab presents, stuff them in the cape, and vanish." They rehearsed their plan quickly, whispering over the fence while eyeing the shimmering pile. "What if parents notice two adults stealing dinosaur wrapping paper and action figures?" "We act natural. Smile, say happy birthday, then sprint like we stole the birthday itself." Time was short before the cake ceremony began. Neither thief wanted to be outshone by a six year old with frosting on his face. "Fine, but if I must twist balloons, you carry the loot." Nevertheless they nodded, inhaled deeply, and prepared to perform together finally.
