W: What’s your address, sir?
M: 4627 North Ellis Street. That’s here in town.
W: That’s a nice neighborhood. How do you like it?
M: The neighborhood is fine, but we don’t like the rent very much.
W: Who does! Just a few more questions, Mr. Crosby. How many people will be included in the coverage?
M: Just me and my wife. What do we do when we want to renew it next year?
W: Just stop by here again next year and let us know. For details on your coverage you can look through our brochure. The policy includes major hospital expenses and doctors’ fees for both you and your wife. By the way, sir, I need your I. D. number. And the name of your department.
M: Well, I’m afraid I don’t have one yet.
W: Don’t have what?
M: A department. You see, I haven’t . . . uh… decided yet what department will accept me.
W: I see. Then, what is your status? You have to be a registered student to get health insurance.
M: Well, I’m almost registered. I’m sure it’s just a matter of two or three days now.
W: Mr. Crosby, I think you’d better wait a couple of days until you get registered. Then come back and complete your application.
M: But what if I get sick today?
W: I’m afraid there’s nothing we can do now. Here. Take a couple of aspirin and hope for the best.
