The rain hammered against the windshield of the van, and Bill was still trying to get the clown wig to sit right in the rearview mirror. "It's crooked," Molly said, not even looking up from the blueprint spread across her lap. It wasn't really a blueprint. It was a birthday invitation with a hand-drawn map of the backyard on the reverse side, courtesy of a very helpful seven-year-old's older sister who thought fifty dollars was a perfectly reasonable price for cartography. "Everything about this plan is crooked, Molly. Why should the wig be different?" "Because you're supposed to look trustworthy. Nobody trusts a clown with a lopsided wig." "Nobody trusts a clown at all. That's the whole point of clowns. They're inherently suspicious. Big shoes, no impulse control, honking things." Molly finally looked up. "Bill, we are stealing birthday presents from a six-year-old named Tabitha. The moral high ground sailed a long time ago." "I'm just saying, if we're doing this, we should commit. Method acting. I want to feel like a clown." "You want to feel like a clown who steals presents from children." "One thing at a time." She rolled her eyes and folded the invitation-map into her jacket pocket. Through the windshield, pastel balloons bounced against a white picket fence, tied there with the manic optimism only found at children's parties and hostage negotiations. A banner reading HAPPY 6TH BIRTHDAY TABITHA sagged slightly in the drizzle, one corner already surrendering to gravity. "Remember," Molly said, "we're not grabbing everything. Just the big pile by the gazebo. The one with the bicycle box." "The bicycle box. Right. The one that's approximately the size of a bicycle." "Exactly like a bicycle, yes." "And how do you propose I fit a bicycle-sized box under a rented clown costume?" "You don't. That's why I'm going in as the face painter. I've got the folding cart." Bill turned slowly, wig tilting further into tragedy. "You get a cart. I get a red nose and the crushing responsibility of distracting forty sugar-addled children." "Thirty-two. I counted the RSVP cards." "Thirty-two children, Molly. Do you understand what thirty-two children can do to a man in face paint?" "They can only do what you let them, Bill." "That's not comforting. That's the opposite of comforting." She reached over and straightened the wig herself, tugging it forward with the tenderness of someone adjusting a crooked picture frame, or perhaps defusing a bomb. "There," she said. "Trustworthy." "I feel like a hostage." "You look like a birthday party. Now get your shoes on. We've got a piƱata to ignore and a bicycle to acquire." Bill sighed, honked the nose experimentally, and reached for the door handle. Outside, a child screamed with what was hopefully excitement, and somewhere a bounce house wheezed to life like a dying accordion. "For the record," Bill muttered, stepping into the rain, "I want it noted that I objected." "Noted," Molly said, already wheeling the cart toward the gate. "Smile, birthday boy's uncle says you do face painting too."
