Night hung like a discount banner over the cul-de-sac where a children's party shimmered with balloons, neon swords, and suspiciously cheerful music. Molly adjusted her scarf, Bill checked a map drawn on a napkin, and both acted like perfectly ordinary adults with fantasies of mischief. The plan unfolded in whispers, jokes slipping between them like a dance. They circled the house, noting the windows that sparkled with party lights, the hedge pretending to be a fort, and the garden gnome that kept an eye on the kitchen door. Molly studied the layout, tapping the napkin. Bill adjusted his hat, grinning with the confidence of someone who has misplaced it three times and found it again. The presents winked from beneath the tree, wrapped in ribbons that looked expensive enough to fund a midlife crisis. They spoke in careful fractions, trading diagonal glances and invented passwords that sounded like grocery lists. The air smelled of vanilla, frosting, and a dare. "We slip in when the cake is plated." "Then we vanish with the biggest bow tonight on the toy train." The night exhaled a sigh, and the two would-be culprits walked away from the glow, rehearsing apologies to the party favors.
