Intro There was a moment when my smoke detector, which is as old as the house it’s in, had to be replaced. And I did that with pleasure, because at that moment it started chirping regularly in a very annoying way. First once every five minutes, a bit later once a minute. And that would not be a big issue had this not been happening at 5:00 AM. And, of course, the chirping was so loud that no human being could ignore it. Just like in that scene from “Friends”.
