Every Thursday night, in the hour or two before my group meets, I get nervous. Excited nervous, as though I'm preparing for a tryst and not a class. It has become the best night of the week, and no matter what else is going on, no matter what other wonderful thing I have on the calendar, I look forward to that moment, that inevitable second...the smile. The smile that at once makes me feel like I've been punched in the stomach and handed a single, sincere daisy. How does he do it?
