When I was a kid, one afternoon we heard a siren go off in the nearby village. What do you do? Well keep doing what you've been doing before. Because it's just a test certainly. Then a voice came on: "This is not a test, not a test." So what did I do then? Scan the houses. And sure enough, there was smoke billowing from a skylight. If I'd been one of the municipal firefighters, I'd run home to grab my gear. Likely my training would have stressed to start running at the first sounding of the siren! Nowadays, if a siren went off at another time of the day, I would leave the building to make sure it wasn't mine being on fire. Maybe that's when I'd get swept away by a flood because I can't distinguish the signals.
