The ‘differential threshold’ is the smallest change
in sensory stimulation that a person can detect.
When you left the room it was barely sensory:
a bee’s wing dropped from fingernail height.
You were drunk, walked cautiously.
To keep the room in place
your fingers brushed the backs of chairs.
When I followed you it was almost invisible:
a candle sunk miles into dusk.
The landscape almost unchanged.
Wine seethed in my throat
I did not touch the furniture.
The party swallowed on; distracted.
We went unheeded, like sugar stirred
through too much water.
You were quiet,
dissolved among the bedded coats.
When I found and kissed you we were
almost unnoticeable, skirting the threshold.
