UMIL: Surprise At The Endodontist

Today, I had one root canal planned for my endodontist appointment.  I had two more planned for Wednesday.  They're all for my front teeth.  So I was quite surprised when he told me the following after my first root canal, "I think we can do two root canals today.  The patient after you cancelled his appointment.  Let's go for it."  I was still sitting in the chair with my mouth open.  I could only nod.  What else could I really do?  Now that I home, it feels like someone punched me in the nose.  UMIL.
