If one were to put a car gearbox in neutral position, start the motor, place a brick on the accelerator, it would only take time to consume a half tank of fuel when a series of mechanical issues presenting serious problems such as over heating leading to ruining the head gasket even the possibility of seizing the engine completely. Why?
If power is contained and not transferred via revolutions of the wheels and no air being forced through the radiator by means of movement, stationary high revving vehicles implode.
If one were to apply this formula to love, then the simile is not any different assuming one is keeping the secret to oneself.
By going and imparting this to whoever it is one is in love with, there may well be a rejection, but a release is experienced and this is what we call a transmission.
