I did it again.
I sat in the office in work for a good 5 minutes wondering why on earth whoever owned the car with the alarm going off wasn't stopping it. Then I wondered: could it be the building alarm?
Of course it was.
I went downstairs to switch it off and spent another 5 minutes getting ever closer to smashing the control panel into a hundred little pieces because it wouldn't stop before I realised I was trying to switch off the fire alarm instead of the building alarm.
I had one of my funny kaleidoscopic eye turns this morning, followed by a headache. I lay the blame squarely there.
