My wife says I can find a topic for a column in the most mundane things. I think she is exaggerating. Anyway, I was walking from the kitchen to my office with a full cup of coffee trying not to spill. It seemed that the more I focused on not spilling, the more likely it was that I would. Caution made my posture rigid, my gait stiff. Slight missteps elicited a jerky correction that set the hot liquid in motion.
