Behind a rhododendron bush, Molly unfolded a plan drawn on a paper napkin. Across the lawn, thirty sugar-crazed children shrieked around a bouncy castle while a mountain of presents glittered on a picnic table. "Phase one, we wait for the balloon clown." Bill adjusted his fake mustache, now drifting toward one ear. "And if he spots us?" "Then we dance. Nobody suspects dancing uncles." So they danced. Bill waltzed out in an inflatable T. rex costume, moving about as quietly as a marching band. He bumped a chair, apologized to it, and wobbled toward the picnic table. Molly trailed him with a laundry basket, humming at a pitch that could curdle milk. A hand-lettered sign warned against touching the presents until after cake. Molly considered this a suggestion. When the clown popped a giant balloon, the kids spun around to cheer. Molly swept every present on the table into her basket in fourteen seconds, a personal record. Bill stuffed the overflow under his tail. They strolled out the back gate, waving to the grandmother who waved back. Back in the getaway van, Bill ripped open the largest box, found a single sock inside, and felt guilty for approximately four seconds.
