When you cut your skin, you bleed（流血）. If a person loses a lot of blood, he will become ill and may die．Blood is very important. People have always known that．At one time, some people even drank blood to make them strong!

When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called " blood transfusion". The blood goes from the arm of the healthy person into the arm of the sick person.

But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood．There are four groups—O, A, B and AB．We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB．But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely.

There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood．At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold．Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time.

We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood．The "blood ban" will give it to you.

　　As I was leaving to meet Lynne, my roommate told me that I'd better take some money, but I didn't listen to him. I thought that Lynne would pay because she had invited me.

　　I arrived at the restaurant exactly on time. I'd been told that Americans expect you to be on time. Lynne and I sat at a table in the corner of the restaurant and a waitress came and took our order.

　　The dinner was a great success. I talked a lot about Saudi Arabia and Lynne told me all about herself. After two hours the waitress finally came and asked if we wanted one check or two. Lynne said two. We went to the cashier (出纳员) and Lynne paid her check (帐单) . I was embarrassed (窘迫的) when the cashier gave me my bill. I had no money to pay for my meal. Then I had an idea. I pretended to look for something in my pockets and said, “Oh! I forgot my money! Can I call my roommate, please?” The cashier showed me where the phone was and I quickly called my roommate.

　　In a few minutes he arrived with some money. But he couldn't hide how he felt. He laughed all the way home. Now, I think it's funny too, but at the time I was terribly embarrassed. I thought that an invitation to have dinner didn't mean the same thing in the United States as in my country. I guess you have to understand that your customs are only your customs. When you visit a foreign country, you have to learn about their customs, too.
