A Village Birthday

Peter and Roberta had the idea. They said to their mum: “Perks is always nice to everybody in the village. Perhaps a lot of people want to give him a gift for his birthday.” They went to every house and every shop in the village and most people wanted to give something for Perks.

The next day, when they knew Perks wasn’t at home, they took the gifts to his house. Mrs Perks opened the door. “We know it’s Mr Perks’s birthday and we want him to have these, “Peter said, and showed her all the bags and boxes. Mrs Perks began to cry. “What’s wrong?” Peter asked. He could not understand why she cried. “I’m crying because I’m happy,” Mrs Perks said. “All these new things! Food to eat, and something for Mr Perks to wear.”

But when Perks came home, he was not happy. He was very angry. “Take these back!” he shouted. “I don’t want you to give me things.” “Why not?” Peter asked. I can’t take all this from you. Perks said more quietly. He knew the children had no money to buy gifts. “But it isn’t all from us,” Roberta said. “Everybody in the village wanted to give you something. You help people and you are their friend. That’s why they gave us these things for you.” “You must take these gifts, Mr Perks,” Peter said, “or everybody in the village is going to be very unhappy.” Slowly Perks began to smile. “Well, I must take them, then,” he said. “Thank you very much. “And he asked the children into his hose for tea.
