Beep, beep, beep, beep

So, I'm working on concert stuff at the moment, so I didn't get to bed until 1am. That was bad enough.

Then at 3am I was woken by a hysterical smoke alarm. I pretty much ran through the house looking for any source of smoke/fire - but alas there was none. I went back to bed a little confused, actually wondering if the smoke alarm had been in my sleep.

Then, one hour later, the alarm went off again. Still no smoke/fire. And it wouldn't stop beeping.

I'd say the battery needs replacing except for the fact the alarm was only installed about two or three months ago.

I wonder if the kids can teach themselves today?
