Ralph: Excuse me, miss. I made an appointment to see Dr. Lee at 3 p.m. this afternoon. My name is Ralph Williams.

Nurse: Let me check, Mr. Williams....Yes, Mr. Williams. Dr. Lee is expecting you. You may go in now.

Ralph: Hello, doctor.

Doctor: Well, what seems to be the trouble, Mr. Williams?

Ralph: It's nothing serious actually, doctor. It's… Well…I get tired very easily recently, and I often doze off during meetings, office hours, sometimes even while I'm dining.

Doctor: How long has this been going on?

Ralph: About two months. I didn't pay much attention to it at the beginning, but you see, I got fired this morning. I dozed off while we were having an important meeting, right in front of the boss. I was very embarrassed.

Doctor: how is your appetite?

Ralph :Pretty good, I'd say.

Doctor: You haven't lost weight, have you?

Ralph: No, doctor. Actually, I've put on two lbs.

Doctor: Unbutton your shirt, please.

(Ralph unbuttons his shirt and the doctor carries out the physical examination.)

Ralph: Well, doctor?

Doctor: You'll have to have some laboratory examinations to know for sure.

Ralph: What examinations?

Doctor: Blood test and urine test. You can come back next week, say sixteen, to see the results.
