This morning I met a man who looked to be - maybe in his mid twenties, at the most, maybe he had just turned thirty. He told me he was in firefighter training school, and then he told me it had been 20 years since high school. My friend and I tried to do some quick math in our heads and nothing made sense. "I'm 40", he said. We just stared at him. I could not think of what to say, at all.
