The speaker is sitting in a hospital waiting room, dressed in a thin gown, about to undergo a procedure on his heart. Across from him sits an older man in the same awkward state. At first they steal glances and look away, embarrassed by their exposed bodies and the tubes in their hands. The speaker even imagines how medical staff must see them: like specimens waiting to be dissected.
Beneath the awkwardness is fear. The poem mentions catheters, stents and bypasses, words the speaker has only just learned. Then the two men smile and talk, and the shared worry becomes a kind of comfort, "like comrades in despair."
The ending turns quietly strange. The speaker thinks that if he died, this stranger's face would be the last he carried. Then he finds comfort in the thought that even his dogs will not remember him for long. The mood is gentle, wry and humbled, accepting how small and temporary a life is.
