You can clearly see out
you can speak, even raise your voice
you think you're being clear, emphatic,
maybe even a bit loud
but actually,
no one hears or sees you
No-ones’ even noticed
you're on the other side of the glass

The curtain,
the veil, the barrier, the obstruction
whatever you want to call it
that distance between you and the rest of the world
the no-mans land between borders
the space in time between receipt of input
and your output
where all the frantic calculations are made
where all the possibilities and ramifications are considered
before blurting out something misjudged
more thought doesn't always lead to a better outcome
you can overdo it
