So far today

Yesterday I went to sleep with my back hurting in the vague hopes it would wear off. Instead the lower back pain is joined by shoulder pain. Joy.

Then the fire alarm box in the hall started going eeeeeeeeeeeeeeeeeeeee.
Someone just now fixed it with percussive maintenance.
... they might have pressed the right buttons, but there was definitely thumping involved.

My confidence in our alarm system would be low except we've had some recent experience of how it performs. So that's nice.
