　　Dialogue 1

　　M: Do I need a visa?

　　W: No, I shouldn’t think so. But you must take your passport of course.

　　M: Yes, I know. I must get my traveler’s check and some foreign currency.

　　W: Yes, you need the traveler’s check but you needn’t get any foreign currency. You can have my US Dollars, I don’t need them.

　　M: Really? That’s very good of you, Helen. But I must get a new suitcase, my old one needs repairing.

　　W: You needn’t buy one. You can have mine.

　　M: That’s very kind of you, Helen. I hope you don’t mind my leaving you like this. I need a holiday. It won’t be long.

　　W: Don’t be silly, John. I’m going with you. It’s necessary for me to have a holiday too.

　　M: Terrible.

　　W: Oh, what’s the matter?

　　M: I’ve got a fever and really a bad headache.

　　W: Oh, that’s too bad. Why don’t you take some aspirin?

　　M: I’ve already tried some but it didn’t help.

　　M: A bus came just as I went to the stop.

　　I love Allen like a brother and except for the times when we’re debating on the court, we’re great friends. It doesn’t necessarily mean that we share the same interests, same CDs, same cloths, etc. A friend doesn’t have to be perfect. We get along well with each other because we both say what’s on our minds. Of course, we disagree from time to time. It’s necessary for friends to disagree since a helpful discussion enlightens our minds. We don’t have to keep peace all the time. But as a necessity, we should respect each other as a person.
