Was I wrong to do what he asked? That is the question I keep asking myself every single night when the house gets quiet and the shadows stretch across the floor.

Mr. Kessler is eighty-two. He is a man who spent his life building things with his own two hands.

Now his hands are thin and shaking and he can barely sit up. I am his neighbor, not his nurse, but I worked in the ward for thirty years. I know what the end looks like. I know the way a person stops fighting.

He grabbed my wrist the first day I came over to change his linens. His grip was surprisingly strong. He looked me right in the eye and said, “Don’t call David.” He made me promise. He made me swear on my own life.

I said I would. I had no reason to think otherwise.

But David calls every afternoon at four o’clock. My phone sits on the counter in my kitchen, buzzing with that insistent, lonely vibration. I know it is him even before I look at the screen. I see his name there and it feels like a physical weight pressing against my chest.

He sounds so young on the phone. “How is he doing, Sarah?” he asks. His voice is always tight. He is trying so hard not to crack. He is polite and he is desperate. He is a man reaching across a decade of silence, trying to find a way back home.

I tell him the same thing every day. “He is sleeping, David. He is resting.”

I never tell him about the hospice nurse. I never tell him about the way Mr. Kessler gasps for breath in his sleep. I just keep the gate locked. I keep the wall up. I am the guard at the entrance to his father’s final days, and I am starting to wonder if I am the villain in this story.

The letter arrived on Tuesday. It was in a thick envelope, handwritten. It sits on my kitchen table right now, just a few inches away from my phone. I haven’t opened it. I haven’t even touched it since I brought it in from the mailbox.

It feels like a live grenade. If I open it, I am breaking my word. If I leave it sealed, I am breaking a man’s heart.

Mr. Kessler is sleeping more today. The hospice nurse came by an hour ago and she didn’t look at me when she said it. She just kept her eyes on the charts. She told me it would be forty-eight hours, maybe less. She said to keep him comfortable.

I went back into the bedroom to check on him. He was staring at the ceiling. He didn’t turn his head when I walked in, but he knew I was there.

“Is he still calling?” he asked. His voice was a thin, raspy whisper.
