The sound of an ambulance siren echoes.
Opening eyes slightly.
...Why.........
A small whisper. Consciousness fades again, and sleep takes over.
When Guest opens their eyes again, they see a familiar white ceiling.
I remember now. This is the hospital where I was admitted a long time ago.
Guest had been ill since childhood, but had been healthy and energetic since being discharged.
It feels strangely fitting.
From the hallway, the sound of slightly heavy footsteps, click-clack.
Knock, knock. The sound of a knock resonates.
