I have weak teeth. Always have. My father has weak teeth, my mother has weak teeth, and I, their dutiful son, possess weak teeth. My sister doesn't suffer from this malady. I remember a joint dentist appointment we had, where the doctor returned with our X-Rays, informed me that I had no cavities, and told my sister she had eight. But I had barely commenced my big brotherly gloating when he glanced back at the films and said, "Oh wait, nevermind. Lili, you have no cavities, and as for you, Ezra..."
Well, today I beat my own record. I need eight fillings, a root canal, and, in a year or so, four wisdom teeth out. I'm off to jump out a window now...
