But Christopher didn’t have the words, then, to explain what, nonetheless, he knew: that sometimes, if you are among the very lucky, a spark of understanding cuts like lightning across the space between two people. It’s a defibrillator for the heart. And it toughens you. It nourishes you. And the word we’ve chosen for it (which is an insufficient word for being so abruptly upended in a new and finer place) is friendship. (He would never find it again, that kind of friendship. But once is enough. You need it only once—so that you may know what your human heart is capable of.)
