Oh, and as I'm sitting with the patio doors etc. open there is, of course, an alarm going off somewhere nearby. It's been going off since 9am, so now over an hour. Sounds like a burglar alarm.
I'm not sure who makes alarms that go off for hours, but really, if someone hasn't responded in five minutes, it's not going to happen, because by that time people are going to start hope the owner did get burgled and then start to create impressively detailed fantasies for their demise.
And you know what happens when any alarm goes off in 2019. It gets ignored, that's what.
Oh wait, it's finally stopped...
