W: So, how are things going, Steve?
M: Well, to be honest, Carla, I was feeling great on Saturday, but I started to feel sick on Sunday afternoon. I thought I’d get better, but I feel worse than before. And I’m even really worse because I’m scheduled to have a presentation at work on Friday.
W: Well, what seems to be the problem?
M: Well, I thought I had a flu, but the doctor said it was just a bad cold. He gave me some cold medicine to take care of my stuffy nose and fever. I’m supposed to take the medicine three times a day after eating, but it doesn’t seem to help. He also told me to stay off my feet for a day or so, but I’m so busy these days.
W: Listen, forget about that medicine! I have just the thing to get rid of bad colds. You see, my mom is really into herbal medicine.
M: Oh, no, thanks.
W: Ah, come on! Give it a try. You just take some of my mom’s herbal tea and drink it four times a day. Believe me. You’ll be up and dancing around in no time.
M: Dancing around in no time, right? Well, I guess, nothing else seems to be doing the job.
W: Great. I’ll come by your place at 7:30. See you then.
