Answers
Answer:
George flashed a pocket torch and saw the boys looking about them. Crossing R.C., Tom wondered if there was anybody in the house. Suddenly George told him that he had already picked three empty houses and had made them sing ‘While shepherds watched’, before he had found out his mistake. Tom replied by saying that it was better than the house with the bulldog.
Suddenly George replied that he was not afraid of bulldogs. Tom recalled him that he bull dog may have torn Alfie’s new suit and once Alfie notices it, he is sure to pick up a fight. Alfie examines his sult. Tom asked how much money they had collected. Ginger counted the pennies and announced that they had just Eight pence halfpenny. After knowing their financial position Tom was very upset, as it was a very less amount to collect after having sung all evening. Well, George told him, it was too early for carol - singing, quickly after Fawkes day was over. Suddenly to heard a loud scream, but George just passed it off as nonsense. Lastly Alfie suggested that all go home.
