"According to Heraclitus, we cannot step into the same river twice. To put it another way, an opportunity lost stays lost forever. While I agree with the spirit of that saying, I have found that the world does allow for some second chances. When Elizabeth's marriage had ended and she returned from England, the waters were still as swimmingly lovely as when we first met. But if time made concessions for love, it made none for death. And when the school's beloved headmaster, Terrence Woodbridge, passed away, I found a sense of profound sorrow. Although the Sedgewick Bell affair tested our friendship, he had been, for a half a century, the academic and moral compass of our school. A role, that was now mine to fulfill."
