A: What's wrong? You don't look very well.
B: Yeah, I had diarrhea last night.
A: Oh, I'm sorry to hear that. How are you feeling now?
B: I am still suffering from slight stomachache.
A: Why did you catch it?
B: I don't know. I guess I had too much at supper yesterday.
A: But I had more than you.
B: Also the soup was too spicy for me.
A: Do you want to take some pills?
B: No, thanks. My stomach is totally empty now. I am afraid pills will make my stomach more uncomfortable.
A: All right. Then you could have some fluid for loose bowels, which may lead to lack of water.
B: Thanks.
A: I suggest you'd better go to see a doctor.
B: Yeah, but later. I'll go to the bathroom now.
