Today's session called for instructor flexibility. At the outset, Will wore a somewhat troubled expression. I asked if anything was wrong. He replied that he was tired for lack of sleep. The reason he gave was that "we got home late last night," a reference to a dinner out yesterday evening. Accordingly, I decided to ease into the session and allowed Will to lead the discussion as he saw fit. The discussion appeared to stimulate him. Observing that he had perked up, I suggested that we move to the question-and-answer period before the Chapter 10 quiz. Will asked a number of good questions, which I answered to the best of my ability. The quiz followed, taking the balance of the session.
