That action completed unexpectedly fast.
Just a very cute sound.
Enthusiastically agreeing to that brilliant idea.
Without any trace of doubt.
The moment when you realize things are weirder than you thought.
Perhaps not really the most unpleasant sound in the world.
Maybe it just never crossed your mind.
A sound that's cutting through the noise like a hot knife in butter.
When things end the way you wanted them to.
