“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.”

“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.”

“While contemplating the bride, and eyeing the cake of soap, he muttered between his teeth: 'Tuesday. It was not Tuesday. Was it Tuesday? Perhaps it was Tuesday. Yes, it was Tuesday.' No one has ever discovered to what this monologue referred. Yes, perchance, this monologue had some connection with the last occasion on which he had dined, three days before, for it was now Friday. ”

“But I didn't understand the middle-of-a-Tuesday Jesus. I only knew him as a when-I-get-to-heaven Jesus. He was my ticket and not much else.”

“When I put my hand on his head,he stepped onto the couch and raised his face to my own. We stared at each other for a few seconds and then slowly,Tuesday licked me. Yes,on the lips...and the chin...and the nose...slobbering all over my face with that big slow-moving tongue. That's the moment when Tuesday,after all his caution,stopped just being my service dog,and my emotional support,and my conversation piece. That's when he became my friend.”

“It's not just his understanding of me, although that's part of it. With a word, Tuesday can guide me to dozens of places. He can be my surrogate or a mirror to my heart.”
