Bill crouched beside the inflatable castle, a decorative shadow. Molly handed him glittery duct tape, like contraband contrails. Inside the house came squeals and the thump of a party playlist, plus the cheerful menace of a clown-shaped piñata warming up. Bill checked his pocket for the “silent” lockpick, which chirped like a kazoo anyway. Molly peered through bubble-gum curtains. “Stay quiet. Kids sleep upstairs.” Bill grinned, confidence brewed from bedtime stories. “Plan: grab presents, vanish fast.” They tiptoed down the hallway, stepping over toy trucks arranged like a game nobody beat. Bill guided the alarm sensor past its blinking light. Molly nodded, mapping escape routes with crayon-bright tape. Molly slid an old balloon arch over her head, turning herself into 'Guest #3' from the printed list. The guard dog barked at squirrels, so they slipped by on luck today. “You grab boxes; I watch.” In the living room, presents sat in a mountain, each tagged with a name: DO NOT TOUCH. Bill’s heart argued with his training. The air smelled like cake and loopholes. “Then we we leave before cake.” They lifted the first box—too bright, too loud—while the party timer started countdowns for 'magic,' somehow sounding like police sirens.
