“Maybe PTSD really is triggered by a single incident, a stressor, as it's known in the psychiatric community, and maybe the attack at Al-Waleed was that stressor for me, but as I have learned in the intervening years, I was not damaged by that moment alone. In fact, while there are specific memories that resurface with some frequency, like the suicide bomber in Sinjar or the order riot at Al-Waleed, I find myself most traumatized by the overall experience of being in a combat zone like Iraq, where you are always surrounded by war but rarely aware of when or how violence will arrive. Like so many of my fellow veterans, I understand now how that it is the daily adrenaline rush of a war without front lines or uniforms, rather than the infrequent bursts of bloody violence, that ultimately damages the modern warrior's mind.”

“‎'After a few seconds, I knew Tuesday was listening. He locked into my eyes, and a calm came over him that I had never seen before. Maybe the part of him that wanted love opened up. Maybe he realized, finally, that this wasn't like any relationship he'd had before. He had been on a treadmill, racing toward each new handler but always ending in the exact spot: alone. He didn't know I was the mission he'd been training for, but at that moment, at the very least, he realized I needed him. And maybe I realized, in my heart and in my head, that this was a two-way relationship and he needed me too. All I know for sure is that when I looked up, everybody was staring at us. Staff, dogs, veterans, everybody. Even the photographer had lowered his camera. Lu Picard told me later that we were together for five minutes, although I could have it was thirty seconds at the most. 'What was that about?' she asked, as Tuesday and I walked post, side by side. 'We're okay now.' I told her. 'We reached an understanding.”

“I am, in fact, committed to being honest with myself so that I can overcome this situation. This includes not succumbing to the path of least resistance (denial) but rather the path of hardship which I know will lead to my evolution.”

“But knowing the difficulties didn't make Tuesday's lack of focus easier for me. When Tuesday was distracted, I felt unsure. In the years ahead, I learned to read his reactions. I knew when his mind was wandering, when he was merely interested in something (Squirrel! Urine-smelling tree!), and when he was alert to possible danger. Knowing Tuesday's mood calmed my mind, because I could trust his vigilance. Today, I can walk down the street distracted and carefree because I have faith Tuesday will alert me to danger. In those early months, before I'd learn to trust his instincts, Tuesday's greatest contribution was his presence. He was my point man, walking slightly ahead of me, symbolically leading the way. He was a buffer against the world, but also a diversion. If they were going to look at me, most people looked at Tuesday first, and that was a relief.”

“Whenever I needed a reassuring touch, Tuesday was there. He was my miracle dog. I already loved him and depended on him more than any other animal I'd ever known- and most other people, too.”

“As always when I was in trouble, I looked down at Tuesday. I could see his concern, but also his confidence in me. There was something about his eyes, when he looked at me, that always said, I believe in you, Luis.”

“Why don't you grab a chair," I joked, "and sit down!"And then, like she so often did, Mary smiled.”
