Molly lay flat in the hydrangeas, peering through a gap in the fence. Bill balanced a cup of orange jello on his chest, taking spoonfuls. The party was wild, a chaos of balloons, screaming, and a clown losing his wig. The present table stood unguarded, stacked like a jeweled fortress. The sun was a smiling sticker on a too-blue sky. Bill licked the spoon. Molly adjusted her socks. Molly whispered, "Present table is at three o'clock." Bill swallowed. "Got the duct tape." She grinned. "Party favors too?" "Everything." They waited until the clown started a magic trick. All children and parents leaned in. Molly counted down on her fingers, mouthing. Bill adjusted his duffel bag. "On my signal." "Three... two... one." They crawled through the grass, low and silent. A small girl wearing a tiara turned. Molly froze. The girl blinked, then pointed at the clown's fake rabbit. Bill slithered to the table. He shoved presents into the bag like a foraging bear. Molly held the bag open. In thirty seconds the table was naked. They reversed, crab-walking, and vanished over the fence. The clown called for a volunteer, and no one saw the empty table until the piƱata burst.
