W: Dr. Carter’s Office.
M: Yes, I’ d like to make an appointment to see Dr. Carter, please.
W: Is this your first visit?
M: Yes, it is.
W: Okay. Could I have your name please?
M: Yes. My name is Ronald Schuller.
W: And may I ask who referred you to our office?
M: Uh, I drove past your office yesterday.
W: Okay. How about the day after tomorrow on Wednesday at 4:00 P.M.?
M: Uh. Do you happen to have an opening in the morning? I usually pick up my kids from school around that time.
W: Okay. Um... how about Tuesday at 8:00 A.M. or Thursday at 8:15 A.M.?
M: Uh, do you have anything earlier, like 7:30?
W:No. I’m sorry.
M: Well, in that case, Thursday would be fine.
W: All right. And what’ s the nature of your visit?
M: Well, to tell you the truth, I fell from a ladder two days ago while painting my house, and I sprained my ankle when my foot landed in a paint can. I suffered a few scratches on my hands and knees, but I’m most concerned that the swelling in my ankle hasn’t gone down yet.
W: Well, did you put ice on it immediately after this happened?
M: Well, yeah. I just filled the paint can with ice and...
W: And so after you removed the paint can ... Sir, sir, Mr. Sehuller, are you still there?
M: Well, that’ s part of the problem. Uh, the paint can is still on my foot.
W: Look, Mr. Sehuller. Please come in today. I don’ t think your case can wait.
