When someone reaches out to you for something important.
It sounds like the system does not obey.
That's how Q.E.D. sounds (latin phrase "quod erat demonstrandum", meaning "thus it has been demonstrated").
That feeling when your calculation checks out (picture the "Success Kid" meme).
This is not the easiest sound to describe.
A provoking and perhaps even exasperating little sound.
A call that suggests concealed intentions.
For real, it is exactly as I described it. Yep, it is.
