"Right," said Molly, spreading the hand-drawn map across the park bench. "The party starts at two." "Got it. What's our window?" "Pin the tail on the donkey buys us four minutes, maybe five if the blindfold's tight." Bill squinted at the map. "What's this circle here?" "That's the bouncy castle. Avoid it at all costs." "Why?" "Kids in bouncy castles have unpredictable trajectories, Bill." "Fair enough. What about the presents?" "Pile's near the back fence. Stack looks enormous. Little Timmy apparently has very generous grandparents." "How do we carry it all?" "I bought a wheelbarrow." "A wheelbarrow." "It's a lot of presents, Bill." "Won't we look suspicious? Two adults with a wheelbarrow at a six-year-old's birthday party?" "I'm wearing a clown wig." Bill stared at her. "That makes it worse, Molly." "Does it though?" "Enormously, yes." "Well, what's your plan?" "I don't know, something that doesn't involve a wheelbarrow and a clown wig." "You've had three weeks to contribute ideas and this is the first objection you've raised." Bill went quiet. "Clown wig it is," said Molly, folding the map.
