Mr. Brown brought with him only a few things because ______ .

W: So Mr. Brown, this is your bed, and as you can see, there are three other beds in the ward. Have you got everything you need?
M: Yes, nurse, I think so. I 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.
M: Yes. Nurse, can you tell me what the visiting hours are?
W: Yes, of course. They are in the afternoon from 2:30 to 4:30 and in the evening from 7:00 to 8:00, but remember that only two people can see you at the same time.
M: I see. What other rules are there?
W: Yes. We start pretty early. We wake you at 6 o’clock, and breakfast is at 8 o’clock, lunch is at noon, there is tea at 3:30, and supper is at 6 o’clock.
M: Oh, that’s very different from what I have been used to. You’d better tell me the rest of the rules here.
W: Yes. Well, you can see the no smoking sign. We don’t allow smoking in the wards, and the same goes for alcohol. However, if you do need to smoke, there are special lounges.
M: Oh, I don’t smoke, so it doesn’t affect me.
W: Good.
