alarm!

so, getting home today, i heard an alarm ringing. bear in mind that i was still 100m from the source of the noise and the radio was going. to figure out where it came from, i switched off the radio, and was astonished to find out that it came from my house! i drove super fast down the lane, hoping that the dog had been left outside and wasn't going mad! i jumped out of the car, relieved to see the dog jumping around me. he was upset, but he hadn't been too close to the noise! raced inside to switch off the bloody machine. couldn't find what had set if off. apparently, everything was as it should have been. the phone wouldn't work, except for telling me what we were being burgled, and could i call someone about it!
