There's an electrician here to fix my burglar alarm. It's been going off for about 5 minutes now. I'm standing right next to it in case he wants me to turn it off again. My ears hurt.

Update: Turns out that whoever originally installed it snapped a couple of centimeters off the end of the plastic anti-tamper button, and stuck a bit of cable flex on the end to extend it. First cold night after the summer must have made it contract - when the sun came up that morning, it flopped off the end and triggered the tamper alarm. It's now got a bigger bit of cable flex on the end while they order in a replacement button.

So that'll be going off again tomorrow morning then. Joy.
