Where are Tim and Kate?

W: Oh, Tim! What happened to you? It’s terrible enough for you to be here.
M: Kate, may be you can’t believe it. It is just because of a little too much smoke. I’ll be back home this evening.
W: How did this happen?
M: I had to go into a house that was on fire. There was still a little girl inside. I got her out.
W: But there was a lot of smoke.
M: Yes, a lot. I had some trouble breathing so they sent me here just for the doctors to take a look at me.
W: And now you tell me that it’s all of your job.
M: Well, it is. You shouldn’t worry all the time.
W: But I do. I hope you’ll leave your job.
M: Leave my job? No, not because of a little smoke. I’m really all right.
