A few weeks ago I was sitting poolside in Florida with a friendly retiree who was standing in the warm aqua water, beaming with friendliness. We started chatting, first about his hometown, Pittsburgh, and the many great athletes from there. Soon the conversation pivoted to Vietnam and his experiences as a draftee there. Embarrassed because I was spared from that jungle and moral crucible, I just listened. First it was a few madcap stories about his arrival in ’Nam, but then his thoughts swam along a darker current.
