“Could you ring Mr Potter, the chief headmaster, sir?” Pete asked him. He hoped that Mr Potter would be more understanding than Mrs Stone. The headmaster said to Pete smiling, “Of course, I can. I know Mr Potter very well. He is a good friend of mine. I’m sure he will listen to your side of the story and help you out. Come on, let’s go to my office and make the call.” The headmaster rang Mr Potter happily. Mr Potter said to him kindly, “Hello, old chap. How are you doing? It’s been a while since we last spoke. What can I do for you?” the head master said yes come round now in person mr potter so mr potter came in person to see Pete happily on foot
