“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.”
