Instance

It is primarily because of the tile
Tile that reaches to shoulder height on the walls
A continued consistency with the floor
Muted reflections of the light-bulb when it is on
Aural reflections in the room
It is cell like and insular
There is a lock on the door
All bodily fluids are contained by the ceramic
A room full of function
Also of empty space
Outside of use it has little aesthetic appeal yet this gives it aesthetic appeal
Frosted window
Vent
Fan
Mats that are out of place on the surface of the floor
A neutral smell when out of use
And scents contained in bottles
Outside a street-lamp that is constant by night
The sound of the wind buffeting the house
The creak of the frame
Cold tile against the feet
If ever there were a first portal
Outside the limits of chronology
This would be it
