I rose early the day I killed my friend. I knew that when I killed him I would have to be ready, could not hesitate or be moved by his suffering, but be ready to strike swift and sure, and for that I needed to prepare myself. I needed not to harden myself but to be strong enough to hold myself open, to measure his pain not with detachment but with empathy, to strike him at the precise moment when the balance between his will and his suffering tumbled irretrievably against him; to allow him his struggle but not to struggle needlessly. I was to honor his final moments by judging when they would be, to do what he would not be able to do, and to give him the honor he was due from me and for himself. I rose early and spent the day in silence, and when I was ready and when the time had come, I took my knife and I went to him.

He did not answer his door; it was too late for that. His disease was untreated and untrammeled, sending the impulses of his nerves to bleed into his flesh, to twitch the muscle and fritter away any semblance of control. A friend let me enter and drew me to the rough mat on the floor, on which our friend sat and shook. I knelt in front of my friend and greeted him; drew my knife for him to see and placed it between us, not as a threat but as a promise, fulfillment of his request and my requirement to end his life.

He turned his head toward the knife and reached out a palsied hand to touch it, jostling it slightly as he did so. Told me it would serve, then reached the same hand to me, bidding me to take it. I found that I could not, the hand holding itself up for long seconds before retreating to its owner.

You blame yourself for this still, said my friend. You blame yourself for this disease you gave me, the one that will kill me today. It sits between us like an unwelcome guest.

I will not ask you to absolve yourself of this guilt. You have willingly picked it up and placed it on your shoulders. Only you will be able to set it down again. But know that I do not ask you to carry it for me. I would not have you think you are unworthy to touch my hand, you who are the only one I can trust and who I will trust in this final hour.

You afflicted me with this disease, took me far from my home and far from the people I love, and brought me to this moment. But you have also called me friend, understood me, and have given me honor and do me great honor now.

You have been long forgiven by me, and all that I would have between us now is companionship and love. You are my last and best friend. Remember that when your burden of guilt weighs you down.

And with those words my friend fell silent, curled himself small and began his wait, holding himself to himself as his body betrayed itself, scattering the messages between body and mind, pushing arms and legs, contorting his silent contemplation into a jester's pantomime, making a mockery of his dignity—but not so much a mockery that his dignity did not hold.

It was hard to watch him leak and spasm and grunt. But I would not turn away. I watched every moment, silent and observant, owing him witness for the affliction I gave him and the release I would yet give him, until the moment when I became aware with every sense that my friend had arrived at his moment of release. I did not hesitate. I picked up my knife and prepared to find his heart.

There is a moment of surface tension when a knife blade presents its demand and the flesh honors it. An instant of pressure before the puncture, the rip before the slide, a small eternity easy to miss but impossible to ignore if you've felt it before. I lived in that moment a great while for the small sliver of time it was there.

And then I moved on, angled my blade in and up, felt its tip pierce its target and slide through the other side, and continued on until the flat of the hilt rested cold on his chest. I moved in close and embraced him, the better to provide leverage to twist the blade, and make the argument to his heart that its work was forever done. The heart did not argue and for that I was grateful.

My friend gripped me as I gripped him, exhaling at the crystal clarity of the knife, cutting through his diffuse and random pain to rally every thought in his body, every final message that coursed along his nerves, toward the goal of reaching his hand to me a second and final time.

I took it and held it, and wet it with my tears as I bent to kiss it, an action which surprised me and released me, and let me lay my burden down. I'm sure my friend saw it in his failing last moment of life; his last gift to me and my last gift to him, so that all that was between us in the end was companionship and love. He died in my arms and holding my hand, and after a minute I set him down on his rough mat, stepped back to where his other friend stood waiting, and gave our friend's soul space to depart.

I did not say goodbye to my friend then, but some time later, as I held his body in my hands, floating in the cold and dark above the brilliant green world of his birth. A place I had come to fulfill a promise: to see him home, to return him to a place from which my actions had kept him while he was still alive. It was not easy to get there and it would not be easy to return, but I had risked my own death for reasons far more trivial. I would not shame my friend or myself by denying him his return home, because it would be inconvenient for me to take him there.

And so I floated above this great green world, body in hand, holding it longer than I should have, whispering words to it that would not carry in the vacuum but which I said nonetheless, before letting it go and releasing it to spiral into the gravity well of my friend's childhood world. My friend and I paced each other a while, sharing the same orbit, until I turned to make my way back to my own world. I did not turn back to see my friend fall away from me. I had said my goodbyes and was content to let him find his own way home.

I wonder if as he fell those he had loved felt him return home and felt his absence filled, as he shot across the sky and spread himself in it. I like to think they did, not because I am the one who took him from them, but because I loved him too, and in loving him felt his love for them. I hope they looked to the sky, saw him move through it, and were glad to have him home.

When you were born all you could do was cry. When I was born I woke to a whisper, giving me a name and telling me to come away from my cradle. I walked, one foot and then another, understanding fully without understanding how I understood. I turned to see my birthmates, all walking and all send' ing out their own names, and receiving names in turn. We were born and we were aware and we would soon be made to fight.

Our childhoods did not exist, except perhaps in the moment between being given our names and setting our feet on the ground. Once that step was taken we had a purpose, a call to action. We answered it unthinkingly, unaware of our options or that there were options—that concept left packed up for the time being because that was what was required in the moment—no more mind than it took to walk, one foot and then another, into the rest of our lives.

When you were two you had learned to speak and walk. When I was two I was made an officer—a lieutenant—to replace the one whose body had been bisected in front of me, dorsal and ventral peeling away from each other and falling sideways, the last thought he sent one of surprise at feeling a cool breeze between his front and back. And I, stumbling back with wounds of my own, holding my arm across my abdomen to keep my insides in, at an age when you were pulling the heads off your sister's dolls.
