The moon hung low over the suburban cul-de-sac, casting a silver glow on the bright red balloons bobbing in the late night dusk breeze. Molly and Bill crouched behind hedges, eyes flicking over the open gate that led to the backyard where children laughed and parents sipped lemonade. The scent of freshly cut grass mingled with birthday cake perfume. They mapped the layout, noting where tiny presents were stacked under the oak tree, and where security cameras hid behind the fountain. Their plan hinged on timing, stealth, and a quick getaway in the rented van parked under the shed soon. Molly: "We need a distraction. The kids will be busy with games, and the parents will be focused on the cake." Bill: "I have a plan. I'll slip in with the cake cart, grab the presents, and exit through the back gate." Molly: "Make sure you don't trigger the alarm. The cameras are hidden behind the fountain." Bill: "I'll use the service tunnel. It's low, and the lights are dim. We'll be unseen." Molly: "Great. Let's move at midnight. The party's over, and the presents are waiting." Bill: "I'll be ready now. We just need to be silent and swift quickly."
