Sometimes the weather gets bad. That can be the end of everyone in it. Accidents can happen easily and quickly. One family once had an accident with some big fish. The fish swam under their boat and bit holes in it. Seawater came in, of course, and the boat soon sank. However, these people had another smaller boat - a lifeboat, and they all got into it. They lived and hoped for many days. They ate and slept, and they always hoped at last a ship found them. How do people live in a very small lifeboat? Perhaps for weeks or months? They must be strong in every way. They must have hopethey must want to live. But you cannot eat and drink hope. You cannot drink seawater. If you drink a lot of seawater, you will quickly die. Sailors can drink rainwater. They must catch rainwater in their boat. They must also catch fish and birds for food. Lifeboats do not often carry a cooker, so the sailors cannot cook their food. Raw fish and bird-meat is not very nice. But in a lifeboat the sailors must eat raw food, or they will die. What do people think about in a lifeboat?

I didnt want to carry too much money with me, so I asked the desk clerk to put a hundred- dollar bill in the safe for me. The next morning, however, the clerk said he knew nothing about my money. I didnt have any proof that I had given the man the money. There was nothing I could do but go to the nearest lawyer. The lawyer advised me to return to the hotel with him and give another hundred-dollar bill to the clerk. This I did. An hour later, I went back to the desk and asked for my money. Since I had the lawyer as an eyewitness to the second hundred-dollar bill, the clerk could not say he knew nothing about it. Another hour later, I put the second part of the lawyers plan into action. This time both the lawyer and I went to the hotel. I asked for the hundred-dollar bill once again, and when the clerk insisted he had already given it to me, I denied（否认）it. The lawyer said to him, “I saw this gentleman give you a hundred dollars. If you dont hand it over immediately, Ill be forced to call the police.” The clerk realized he had been tricked, so he gave me back the first hundred-dollar bill. “I dont know how to thank you enough for getting my money back,” I said to the lawyer. And what you suppose he answered? He said, “Oh, dont thank me. That will be a hundred dollars, please.” 46. The man went to a Detroit hotel one day to_.
