W: Okay. How about the day after tomorrow on Wednesday at 4:00 o’clock?
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. Urn... how about Tuesday at 8:00 A.M. or Thursday at 8:15 A.M.?
M: Well, in that case, Thursday would be fine. And my phone number is 643-0547.
W: Alright. And what’s the nature of your visit?
M: Well, to tell 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’m most concerned that the swelling in my ankle hasn’t gone down yet. Uh, the paint can is still on my foot.
W: Look, Mr. Schuller. Please come in today. I don’t think your case can wait.
