The van smelled like old pizza and nervous sweat outside the suburban house. Molly whispered, "Bill, we need a plan to grab those birthday presents fast." Molly peered through binoculars at streamers while Bill polished his crowbar. Bill muttered, "Relax Molly, I brought balloons, fake mustaches and a giant empty bag." A chorus of shrieking children echoed from the backyard bounce house. Molly giggled, "Perfect, we sneak in during pinata time when parents look away." Bill fidgeted with his party hat as sprinklers hissed across perfect grass. Bill asked, "What if the clown recognizes us from last Easter egg disaster?" Molly snorted and smeared extra glitter on her fake tired mom disguise. Molly ordered, "He won't, just act like tired parents desperate for free cake." A dog barked loudly next door while someone dropped an ice cream cone. Bill sighed, "I love cake, Molly, but stealing toys feels weirdly mean today." He stared longingly at the tower of bright presents inside. Molly hissed, "Focus Bill, those wrapped Legos could pay our rent for months." Bill offered, "Okay, you distract the magician while I grab everything quickly." Molly warned, "Deal, and no sampling frosting until getaway car starts moving." "Agreed totally!"
