W: So Mr. Baker, this is your bed and as you can see there’re five other beds in the ward. Have you got everything you need.’?
M: Yes, ! think so. l followed the hospital’s advice and I’ve only brought a few belongings with me.
W: Good! You can see the reasons why we ask you to do that; the cupboard is really very small. And have you arranged for anyone to bring in changes of nightwear and other clean clothes?
M: Yes, my wife will deal with all that. Can you tell me what the visiting hours are?
W: Yes, of course. They’re in the afternoon from 2:00 to 3:00 and in the evening from 7:30 to 8:30, but remember that only two people can see you at the same time. Sony about that but you can imagine  the chaos if we didn’t have these rules!
M: Yes, I suppose so. What other rules are there?
W: Well, first of all I should tell you about our hours. We start pretty early—you might not be used to that. We wake you at 6:30, and breakfast is at 8 o’clock, lunch is at noon, there’s tea at 3:30 and supper is at 6 o’clock.
M: Oh, my goodness! That’s very different from what I’ve been used to. Still, I won’t be here for long, I hope. You’d better tell me the rest of the rules.
W: Yes, well, you can see the no-smoking sign—we don’t allow smoking in the wards under any circumstances,  and the same goes for alcohol. I’m sure you understand why. However, if you do need to smoke there are special areas when it’s allowed.
M: Oh, I don’t smoke, so it doesn’t affect me. And I think it’s a good rule. Do you smoke, nurse?
W: Er, no! But l used to. !’ye given up in fact. 1 haven’t had a cigarette for three months now.
M: Well done! kook, I mustn’t keep you any longer, but just one more question—can I make a telephone  call? I mean, is there a phone anywhere?
W: Yes, of course there is. Outside the ward there’s a payphone. You need changes for that of course.
M: Oh, and that reminds me’"
W: Can you make sure that only one of your relatives’ phones in each day to find out how you are? The switchboard gets congested with callers. M: Yes, OK.
W: I must go now. You get changed and into bed, and I’ll check on you in a while. The radio controls are there, with your own headphones, if you want to listen. It’s our own hospital radio.
M: Thanks very much. You’ve been very helpful.
