Molly leans against a weathered playground slide, Bill twisting a sticky swiped lollipop. “You sure the party’s Saturday at 3?” “Dead sure—my cousin’s kid blabbed the whole schedule, down to the pinata’s candy fill.” “Presents stashed where?” “Pantry off the kitchen—mom’s paranoid about kids tearing ’em early, locked the door with a flimsy hook.” “How we get in?” “Back fence has a loose board—sneak through when the pinata drops, everyone’s too busy screaming to notice.” “What about the poodle Fluffy?” “Loves peanut butter; I’ll leave a stuffed kong by the gate to lure her away for an hour.” “Kid wanders in?” “Fake a clown costume—say I’m here to fix a broken present.” “You can’t fit a clown costume.” “I’ll hem it—stole a sewing kit last week, practiced on an old towel.” “Presents fit in backpacks?” “Most—big bike’s a problem; I’ll tie it to my scooter outside.” “Cops?” “Neighborhood’s lazy—no one calls unless there’s a fight.” “Meet me at 2:45 by the fence?” “Yep—bring extra tape for backpack zippers.” “Don’t forget peanut butter.” “Won’t—stuck it in my pocket this morning.” “Flimsy pantry hook?” “I’ll slip a bobby pin to pop it—stole a pack from a drugstore counter yesterday.” “Don’t mess up the pinata timing.” “Won’t—my cousin’s kid texted me the exact minute it’s being hung.”
