"Right, the party starts at two," Molly said. "Cake at two-thirty. Presents at three." "So we go in at two-thirty." "We go in at two-forty. Nobody watches anything during cake, Bill. Cake is a religious experience for the under-tens." "And the parents?" "Photographing the cake." "What about the entertainment?" "A magician. Gary the Great." "Gary the Great's a grass." "Gary the Great owes me forty quid, which is why Gary the Great is going to do a very long trick with a rope at two-forty." "And I'm the balloon man." "You're the balloon man." "Molly, I can't make balloon animals." "Nobody can make balloon animals. You make a sort of long twisted thing and you say it's a giraffe, and if anyone argues, you say it's abstract." "To a six-year-old?" "Especially to a six-year-old. They respect confidence." "And the presents go where?" "Bin bags. Two trips. Out through the side gate, into the van, gone before they've blown the candles out." "Feels wrong, robbing a child." "It's a bouncy castle in Surrey, Bill, not an orphanage. That boy's getting eleven scooters." "Eleven?" "His mother posted the list." "...Fine. But I'm keeping one scooter." "You're forty-six." "I'm keeping one scooter."
