Floating at night
The hospital, with all its activity and mad transformation, is subdued at night. A cover is dropped over everything.
But it is not as if everything goes to sleep. The activity is dampened but not stilled, like music heard outside a soundproofed room.
Even those events that happen in a mad rush - the resuscitation, the emergency surgery - feel slower. It is night's recognition that daytime matters. Not every shift is like every other.
