What the silence is made of
It is not one thing, and they do not want the same thing
Completely different events read as the same word. Each gets its own scene, and the view from the other chair.
The one that arrives in four seconds
A conversation going fine, and then it is not. His hearing has narrowed, his hands have gone cold and the sentence he was halfway through has genuinely gone. Nothing is being decided.
From where he is sittingHe leaves the room because he can feel himself about to say something he cannot take back.
The man who has never had the words
Not withholding them. Never taught them. No one has ever asked him what anything was like, so there is no practised route from the inside of him to the outside.
From where he is sittingA question about how he feels is an exam in a subject he has never sat.
What he thinks would frighten you
A letter, a debt, a job that is going, something from long before you. The silence is protective in intention, and doing real damage while it protects.
From where he is sittingHe has decided you have enough on, and that carrying it alone is the decent thing.
Shame, which has no vocabulary
There is no sentence for it that does not sound worse out loud than it feels inside. So nothing is said, and the nothing gets read as not caring.
From where he is sittingSaying it would make it true in the room, and true in front of you.
The hour after, for a man who was shouted at as a child
A raised voice puts him somewhere he was at nine years old. The hour that follows is not sulking and it is not a tactic; it is a body coming back down.
From where he is sittingHe is waiting to be sure the room is finished before he walks back into it.
The one that is doing something
This one is in here too, named plainly rather than explained away: silence used as a correction, or to leave you holding something on your own. It is not the same as the others and it does not get the same patience.
What this one isThe honest question here is not what he is carrying. It is what you are prepared to live with.
