In 2011, my family was in a major car accident. We were hit head-on by a man in the throes of a heart attack. It took three years to recover from our injuries, and a couple more to deal with the aftereffects of trauma. When I finally returned to the world — as father and husband, friend and brother, writer and citizen — it became clear that our society was in its own traumatized state — reeling from the string of police shootings of unarmed African Americans, stunned by yet one more mass shooting. The people around me were displaying all the signs of PTSD — jumpiness, irritability, numbness — and, concordantly, my interactions out in daily life were becoming more dysfunctional, at times downright hostile. Us against them. Red vs. blue. Black vs. white. Rich vs. poor.
