A standby situation like a dripping tap, the sound of a refrigerator, a stationary airplane: as if an event is hibernating. That gives the feeling something is present, an act was done, an achievement managed or that something is coming. This kind of situation is the framework/chassis from where an event is build up or broken down. The event acts as a decoration, an achievement or a failure of this framework. The process of building up or breaking down is one of collision, leakage and vacuum.
