The Matter of Shared Silence Check
Two people have been sitting together without speaking for a comfortable amount of time. One of them has just asked if everything is okay.
The silence had been going on for eight minutes.
Both people were present. Both were doing something. The silence was of the kind that does not need filling. This kind of silence requires some trust between the people involved, and the trust was present.
At eight minutes, one person said: "You okay?"
The Question's Effect
The question was well-meaning. It came from care: a sudden awareness that the other person had been quiet, and a check to ensure the quiet was comfortable rather than the other kind.
The question was also an intervention in a silence that was fine. The silence was fine up to the moment the question was asked. The question introduced the possibility that the silence had a reason, which the silence had not, but which now needed to be ruled out.
"Yeah, why?" is the correct answer. It rules out the non-comfortable version of silence. It also invites the questioner to examine why they asked, which may reveal that the question was about the questioner's comfort with the silence rather than the other person's.
The Meta-Silence
After the question was answered, a new silence began. The new silence was of a different character: slightly self-conscious, both parties now aware that silence can be questioned, and both briefly monitoring whether the current silence needed another check.
The second silence was approximately two minutes, shorter than the first.
The Comfortable Silence Threshold
The threshold at which comfortable silence becomes questionable varies by relationship. Close relationships: longer comfortable silence tolerance. New relationships: shorter. Long-established relationships with a slight emotional distance: variable and dependent on recent history.
Eight minutes was, for this relationship, within the comfortable zone. The question was the only thing that changed that.
