W: You don’t look too well. Maybe you should take the day off from work.
M: (23)I couldn’t do that. I have an important meeting to go to today.
W: Do you feel OK?
M: Not really. After a 12-hour flight, I’ve got the jetlag, and on top of that, I think I’ve also got the flu.
W: (24)Why don’t you call your secretary and tell her to reschedule the meeting? You should really take a rest at home or you’ll end up feeling even worse than you do now.
M: Could you feel my forehead and check to see if I have a fever?
W: You’re really hot. Let me get you some Tylenol to bring the fever down.
M: OK. I’ll stay at home this morning and take a rest, but if I feel better in the afternoon, I’m going to the meeting. (24)Now I’ll call my secretary.
W: Gosh, what’s that on your arm?
M: I don’t know. It looks a bit red, but I’m sure it’s nothing.
W: It looks like you have a red rash! Are you allergic to anything?
M: (25)Just cats, but I don’t think I was near any cats in the last couple of weeks.
W: I completely forgot about your cat allergy. (25)I took care of a cat for my friend here a few days ago. Oh no, we’d better go to the doctor to get some medicine. Let’s go.
M: Shouldn’t we make an appointment first?
W: We should, but let’s just go and see if there’s an opening now before it gets worse.
