“Individual heart cells beat at their own rate when separated from one another, a phenomenon easily observed beneath a microscope. It has long been known that when they are pushed together, they will synchronize their pulses. Recent studies have shown, however, that heart cells begin to synchronize slightly before they touch. It is not known how they signal across this distance. Some scientists speculate that this method of communication may be able to cross great distances and may explain how social animals bond, or how pets seem to sense when their masters are coming home, or even how people fall in love, one heart calling to another.”

“No animal has a heart quite like a dog's”

“A newspaper story, like anything else, is more attractive from a distance, when it first comes to you, than it is when you get in close and agonize over the details. Which I presume is how Yardley got in the habit of keeping himself at a distance.”

“You said you're going far away," Tamaru said. "How far away are we talking about?""It's a distance that can't be measured.""Like the distance that separates one person's heart from another's.”

“But that was the last time. That was…how should I say it? ... the one moment in my life when I was able to draw closest to Eri ... the one moment when she and I joined heart to heart as one: there was nothing separating us. After that, it seems, we grew further and further apart. We separated, and before long we were living in different worlds. That sense of union I felt in the darkness of the lift, that strong bond between our hearts, never came back again. I don't know what went wrong, but we were never able to go back to where we started from.”

“Sadness pulses out of us as we walk. I almost expect the trees to lower their branches when we pass, the stars to hand down some light. I breathe in the horsy scent of eucalyptus, the thick sugary pine, aware of each breath I take, how each one keeps me in the world a few seconds longer. I taste the sweetness of the summer air on my tongue and want to just gulp and gulp and gulp it into my body--this living, breathing, heart-beating body of mine.”

“How curiously one is changed by the addition, even at a distance, of a friend. How useful an office one's friends perform when they recall us. Yet how painful to be recalled, to be mitigated, to have one's self adulterated, mixed up,become part of another.”
