It happens often enough to confirm that I am human and not some amped up version of a good citizen or exemplary judge. Watching someone walk away from an encounter with me and I suddenly realize I could have said or done something profoundly caring. The thought that my contact also recognized the missed opportunity is less rattling . A heart that recognizes that a moment of glory just slipped by is in good shape. So this kind of anxiety has an accompanying comfort. Even the criminal and uninformed person wants to be known as caring for another person. The brightest lights of human life shine with caring activity.
