Roll After Dark

Being left waiting

Left in place, in a corner, or in a tie, with time as the point.

Why people do it
Nothing happening is the content. Time alone in a position turns anticipation into the whole scene, and for people who live in their heads it is often more intense than sensation is.
Smallest way in
Five minutes in a corner while you make a coffee. That is genuinely enough to find out whether the empty room does anything.
What to watch
A person who is tied or gagged is never left alone, full stop. If you want them tied and waiting, stay in the room and be quiet — that is a different thing and it works just as well.
In the planner
11 different things carry this tag, and switching it off removes every one of them. The mildest of them sits at easy.
