What is it about men and finishing things?

I had my follow-up at Hines today for my tooth. The dentist stated that even though it had broken, it should be saveable. The partial root canal the dentist started two weeks ago was supposed to be finished today. Instead, they did a partial root canal, AGAIN! I have no idea what they did last time, except it involved drilling holes. This time, they took the broken portion of my tooth out and then drilled some more. I am waiting for them to call me to schedule a time to finish the job, but not holding my breath.
