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. Ullu: Why don't you send him an e-mail? Leo: I can't.

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.
