And to whom am I speaking?

It is possible to believe that the receptionist at the doctor's remembered that you called the day before to ask about the details of your appointment in such a way that she had to respond, with the kind of tired, deliberate manner that you hadn't heard outside of the theatre: and to whom am I speaking? It is possible that she remembered you because she had made a caustic note against your name when your answer failed to adjust to the seriousness of her tone. It is highly unlikely that she recruited the oldest and sickest to fill all the chairs in reception so that you had to stand out in the corridor when you arrived, but not entirely implausible that she went on that day to draw strange pointed shapes in the register next to your name with the fat-bodied pen that she was not even thankful you returned.
