“My son slept here.” He looked up at me with wide eyes.

“Is he ever coming back home?” And I stood in the doorway of my dead son’s bedroom, looking at a living boy I did not yet dare to hope was him, and I could not answer.

I have thought since about the strangeness of that question — is he ever coming back home — asked by a boy who was, though neither of us knew it yet, the very child he was asking after.

He stood in his own nursery, looking at the growth marks his own mother had made on the wall when he was two, asking a grieving stranger whether the little boy who had slept there would ever return.
