A year later, Kabbu was sitting with Ullu and talking about the good old days. Just then they saw Bony. He *hurrying somewhere. 40 was Ullu: What happened, Bony? Where are you going? Bony: I heard there was an *accident near Leo's house. I am going there. Kabbu: Accident! Let's go! They hurried as fast as they could and saw Leo. He was walking around *worriedly. Leo: My son fell down from a tree and hurt his head. He needs an *operation by Dr. Large, the best doctor in this forest. 15 Ullu: Why don't you send him an e-mail? Leo: I can't. There has been something wrong with my computer since last night. We have [way/ come/ask/to/no other/him] here. We will have to wait about three days to *repair it. But I can't wait so long. My son needs an operation right now! Kabbu: That's no problem, Leo. I will go and bring Dr. Large here. Leo: Really... w... will you go right now? Kabbu: Of course! Until last year it took from here to Dr. Large. But Leo, this is an *emergency! I'll bring Dr. Large in half the time. He was right. Four hours later, they saw Kabbu and Dr. Large. They were flying in the sky. They looked very tired. Soon he began to operate on Leo's son. Leo: How's my son, Dr. Large? Dr. Large: 8 about/is/there/to/worry 1. Your son is all right. You should thank Kabbu. I think he has done a great job. I was at home when he appeared in front of me. He didn't give me any time to think about it. I said to him, "You have just arrived after such a long and hard trip. Take a *rest for one or two hours and then we'll go." But he didn't agree. "No, Dr. Large. There is no time to lose," he said. Later... Leo: My dear friend, Kabbu, I don't know how to say thanks to you. You are so kind to me and my family. You lost your job because of the Internet, but you didn't feel angry with me and saved my son's life. New technology may make life easier and give us more fun in many ways, but sometimes it may not be useful and sometimes we can't depend on it.
