John Green was looking forward to Christmas. John Green was looking forward... with dread... to Christmas. He'd been recruited as an ersatz teacher last year, to help Sharon and her classmates perform their Nativity play. Unfortunately, he'd made such a good job of it that Mrs Forrester had decided that the other children at the school would also benefit from his help preparing for their Christmas show. Then, of course, John had also been recruited as a swimming instructor. He already spent a day a week at the school. How much more time would his new role require? He wasn't sure he had sufficient spare time to get everything, and everybody, prepared! But John Green had a plan... If he hadn't got enough time, maybe he could make some more? Maybe a trip to the holiday home would help? Nothing could go wrong! Could it? Time would tell... Urni certainly wouldn't!
